Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses an IP address resolution method, a system, a device and a computer readable storage medium, which aim to solve the problem of how to resolve IP addresses of both IPV4 type and IPV6 type.
Referring to fig. 1, an IP address resolution method provided in an embodiment of the present invention specifically includes:
s101, receiving an address resolution request.
Firstly, an address resolution request is received, wherein the address resolution request is a request for resolving a domain name into an IP address, and the request comprises the domain name to be resolved. The address resolution request may be an address resolution request sent by a DNS (Domain Name System) resolution service component, which includes PDNS, i.e. PowerDNS, and is an open source DNS service component across platforms.
It should be noted that, when a client requests to establish a connection with a cluster server, a domain name is usually input by the client, a DNS resolution service determines an address resolution request by using the domain name, and then sends the address resolution request to a system, and the system resolves the domain name.
S102, determining a target IP address corresponding to the address resolution request.
And finding the IP address corresponding to the domain name according to the domain name information in the address resolution request, and taking the IP address as a target IP address.
It should be noted that, for the same service cluster, the same domain name is represented to the client, but the cluster includes a plurality of nodes, and the IP address of each node is different.
When a large number of user clients access the cluster, if the target IP addresses determined for all the clients are the same, a situation that one cluster node establishes connection with a large number of client lists occurs, thereby causing a problem of load imbalance of the cluster. Therefore, when a target IP address is determined for one address resolution request, different IP addresses need to be allocated to different requests, so that different clients are connected to different nodes, thereby avoiding the situation that a cluster node load is unbalanced because one node is connected to a large number of clients.
Therefore, in the scheme, two modes of determining the target IP address can be adopted, namely the target IP address can be determined in a polling mode, and the target IP address can also be determined by a connection number method.
The polling mode is to determine the target IP address determined when the analysis request is received last time, then determine the next IP address of the last target IP address, use this IP address as the target IP address, and determine the target IP address sequentially and circularly downwards when the request is received again.
The number of connected clients is determined, and the IP address of the node with the least number of connections is used as the target IP address, so that the client corresponding to the address resolution request establishes connection with the node with the least number of connections.
For the methods corresponding to polling and connection number, reference may be made to the prior art, and not described herein in any greater extent. However, in the present embodiment, since the resolution of the IPV6 type IP address is compatible, the IPV6 type IP address generally has multiple formats, that is, multiple representation methods, for example, colon representation: 2001:0250:3000:1000:0000:0000: 0005; 0-bit compression representation: 2001:250:3000:1000: : 5; inline IPV4 notation: : : FFFF: 192.168.0.1.
in the connection number method, if the IP address corresponding to the cluster node is an IPV6 type, and there are multiple IPV6 type representation formats, so when a client establishes a connection with a cluster node corresponding to the same IPV6 type IP address, the representation format of the IP address used by each client may be different, but the IP address actually corresponds to the same IP address, and therefore, in order to better count the number of connections, it is necessary to determine the IP address used by each client first, that is, determine the IP address at which the client establishes the connection first, and if the IP address is an IPV6 type, it is necessary to convert the IP address into a target format and then perform statistics. Therefore, the same IP address of the IPV6 type with different representation formats is converted into the same IP address in format, so that the number of connections corresponding to one IP address is more convenient to count.
The specific introduction of the method for counting connections applied in the present solution will be specifically described in the following embodiments, which will not be described herein again.
S103, determining the type of the target IP address, wherein the type is an IPV4 type or an IPV6 type.
Specifically, in order to make the resolution service compatible with the IP addresses of both IPV4 and IPV6, after the target IP address is determined, it is also necessary to determine the IP address type, that is, whether the target IP address is IPV4 type or IPV6 type. IPV4 type is A and IPV6 type is AAAA.
S104, returning the target IP address and the type of the target IP address to a receiver so that the receiver processes the target IP address according to the type of the target IP address.
It should be noted that, if the type corresponding to the destination IP address is not sent, when the IPV6 type address returns to the DNS resolution server, the server will process according to the IPV4 type IP address, and at this time, an error occurs, which causes a problem of failed resolution. For example, the PDNS may timeout when communicating with the loadbalance, and the PDNS may restart the loadbalance.
Therefore, in order to be compatible with the IP address of IPV6 type, in this scheme, the target IP address and the type corresponding to the target IP address need to be sent to the receiving party together, so that the receiving party can distinguish the IP address of IPV6 type from the IP address of IPV4 type, thereby avoiding the problem of failed resolution.
Therefore, according to the IP address resolution method provided in the embodiment of the present application, after the target IP address corresponding to the address resolution request is determined, the type of the target IP address is further determined, and both the type and the target IP address are returned to the receiving party, so that the receiving party can distinguish the IP address of IPV6 type from the IP address of IPV4 type, the problem of resolution failure is avoided, and the compatibility of IPV6 and IPV4 is effectively ensured.
A specific IP address resolution method provided in this embodiment of the present application is described below, and a specific IP address resolution method described below further defines and explains determination of a target IP address in the foregoing embodiment, and other steps are substantially the same as those in the foregoing embodiment, and specifically refer to the foregoing embodiment, and details will not be described here.
Referring to fig. 2, a specific IP address resolution method provided in the embodiment of the present application specifically includes:
s201, receiving an address resolution request.
S202, determining a target node IP address with the minimum connection number by using the connection number information corresponding to each cluster node IP address; the connection number information comprises cluster node IP addresses and corresponding connection numbers, and the connection numbers are the connection numbers which are monitored by utilizing a preset IPV6 interface and a preset IPV4 interface in real time and establish connection with the IP addresses of the cluster nodes.
In the scheme, an IPV6 interface and an IPV4 interface are added in advance, the two interfaces are respectively used for monitoring the connection number corresponding to the IP addresses of cluster nodes of different types, the IPV4 is used for monitoring the connection number corresponding to the IP address of the cluster node of the IPV4 type, and the IPV6 is used for monitoring the connection number corresponding to the IP address of the cluster node of the IPV6 type. The IPV4 interface can refer to the prior art, and the IPV6 interface can be realized by adding 'udp 6 [: ]: 1662'.
It should be noted that monitoring and storing the connection number corresponding to each type of current IP address may be performed in real time or at preset time intervals, but the operation of determining the target IP address with the minimum connection number in all cluster nodes is performed after receiving an address resolution request, that is, after receiving the address resolution request, the target node IP address with the minimum connection number is determined from the monitored information.
It should be noted that, if the IP address corresponding to the cluster node is of an IPV6 type, and there are multiple IPV6 types of representation formats, so that when a client establishes a connection with a cluster node corresponding to an IP address of the same IPV6 type, the representation format of the IP address used by each client may be different, but the IP address used by each client substantially corresponds to the same IP address, and therefore, in order to better count the number of connections, it is necessary to determine the IP address used by each client, that is, the IP address at which the client establishes the connection, and if the IP address is of an IPV6 type, it is necessary to convert the IP address into the same target format, and then perform statistics. Therefore, the same IP address of the IPV6 type with different identification formats is converted into the same IP address in format, so that the number of connections corresponding to one IP address is more convenient to count.
Therefore, in a specific embodiment, connection information corresponding to an IP address of each cluster node is first determined, where the connection information includes IP address information used by a client to establish a connection with a cluster;
converting the IP address of the IPV6 type in the IP address information into a target format;
counting the number of clients connected with the IP address of each cluster node, and taking the number as the connection number of the IP address of each cluster node;
and taking the cluster node IP address with the least connection number as a target IP address.
S203, determining the type of the target IP address, wherein the type is an IPV4 type or an IPV6 type.
S204, returning the target IP address and the type of the target IP address to a receiver so that the receiver processes the target IP address according to the type of the target IP address.

S304, returning the target IP address and the type of the target IP address to a receiver so that the receiver processes the target IP address according to the type of the target IP address.
S305, receiving the target IP address sent by the receiver.
It should be noted that, in the practical application of domain name resolution, besides the forward resolution mentioned in the above embodiment, that is, determining the IP address according to the domain name, there is also the reverse resolution, that is, determining the domain name by the IP address.
In the scheme, the system returns the IP address obtained by forward resolution to the receiver, namely the DNS resolution server, and then the receiver can also send the received IP address back to the system to verify whether the domain name corresponding to the IP address is the domain name which the client requests to access.
Specifically, the target IP address sent by the receiving party is received first, and the target IP address is the forward-resolved target IP address returned by the system to the receiving party.
S306, when the target IP address is an IP address of an IPV6 type, converting the target IP address into a target format.
Since IP addresses of IPV6 type come in a variety of formats, in order to facilitate matching of IP addresses to domain names, it is necessary to convert IP addresses of IPV6 type to a destination format.
S307, determining domain name information corresponding to the target IP address in a configuration file by using the target IP address in the target format.
Specifically, the corresponding domain name information may be determined in the configuration file by using the target IP address in the target format. It should be noted that, the configuration file is provided with a corresponding relationship between the domain name and the IP address, and the parsing operation can be completed according to the configuration file.
