Embodiment
In order more to be expressly understood technology contents of the present invention, describe in detail especially exemplified by following examples.
See also shown in Figure 1, in the prior art, when selecting internet address, in browser, indicate http: // the back import corresponding internet address with forms such as letter, numeral, hyphens, this address is converted into the key of numeral by means of the name server in the Internet (DNS), be so-called IP address (Internet protocol address), and rise and to be dynamically connected.
DNS is the translated name of Domain Name System, and it is a kind of at branch's formula NetWare directory services NetWare of realizing on the internet that domain name addresses and address are translated mutually.Be used for domain name is translated into the IP address that computer can be discerned.For example, if there is the people will visit the website (www.sohu.com) of sohu, DNS just is translated into IP address 61.135.132.3 to domain name.Facilitate like this and search the proprietary Website server of domain name.
Name space is designed to tree, from tree root (root), is the TLD of using always (gTLDs) subsequently, as " de ", " com " or " org ".They further are divided into subdomain.
The DNS of name space management contains the zone of all following branches of a node in the name space tree and this node.By the name server on the different depth of tree, the zone of different DNS overlaps mutually.A DNS discerns than its higher DNS with than its lower DNS.
The main task of DNS is to give domain name or opposite with IP address assignment, user program (for example browser) can not oneself be finished this inquiry (inquiry), this service that most of operating systems are integrated, user program can call these information that obtains by means of operating system.Resolver (Resolver) is born the inquiry to DNS, and in order to raise the efficiency, all resolvers have a Cache (intermediate store), thereby they can the rapid answer multi-retrieving.
The DNS query script of a standard is as follows:
(1) user program has a domain name, and wishes to obtain the IP address of this domain name correspondence;
(2) user program sends one and inquires resolver and wait for that its responds;
Whether the resolver inspection replys in Cache, if resolver can pass this and reply
Do not occur in Cache if reply also, then resolver sends one and inquires a DNS in one side
(3) DNS replys to the resolver foldback is desired
(4) resolver duplicates this and replys in its Cache, this is replied send user program to simultaneously.
See also shown in Figure 2ly again, may have following situation in carrying out the process of DNS inquiry: first DNS that is inquired about does not reply the inquiry that resolver proposes, exist in the case two kinds may:
First DNS that is inquired about seeks voluntarily and can make other DNS that replys to this inquiry, and in this case, resolver does not change, and it just waits for, until being replied from " it " DNS, this query mode is called as " circulation ".
Circulation DNS query script is as follows:
(1) send an inquiry by resolver and give certain DNS, also comprising this inquiry in this inquiry should be by the information of " circulation " execution;
(2) if first DNS that is inquired about does not show that this DNS continues this inquiry is forwarded to another DNS to the replying of this inquiry, wherein first DNS that is inquired about guesses that this another DNS can provide and replys
(3) if this DNS does not show yet to be answered, it returns this message foldback and whether it of announcement knows that may provide a DNS who replys, and this process can be repeatedly repeatedly.
(4) first DNS arrives at a DNS who knows this answer at last, and this is a so-called authoritative domain name server for a most applications.
(5) replying by foldback of this inquiry returned resolver.
If first DNS can not propose answer for the inquiry to it, then another DNS is with recommended, and resolver must be inquired about this DNS again.This process can be repeatedly repeatedly, and until DNS of last parser queries, it can provide and reply.
In existing browser network element structure, import the user under the situation of right-on network address, resolver is with correct IP address of foldback, when the network address of user input is incomplete, domain name corresponding to this network address is also imperfect, resolver is with error message of foldback, and the user then can't obtain needed IP address.
See also shown in Figure 3ly again, the method for this searching internetwork address on computer comprises client, by resolver and several name servers that network is attached thereto, and wherein, described method may further comprise the steps:
(1) with network that client is connected in additional its domain name matching database of domain name coupling add-on module continuous updating;
(2) according to the domain name that the user imported, described client is sent query requests to this resolver;
(3) this resolver is checked the pairing IP of this domain name address whether in its Cache, if then this resolver comprises replying of this IP address with this and is back to client;
(4) if not, then this resolver carries out above-mentioned circulation DNS query script described in the prior art to this domain name by described several name servers;
(5) if this resolver has obtained replying of corresponding IP address in this process, then this resolver duplicates this IP address in replying in its Cache, simultaneously this is comprised replying of this IP address and is back to client;
(6) if this resolver does not obtain replying of corresponding IP address in this process, then this resolver carries out the DNS matching operation to this domain name by described domain name coupling add-on module, and this DNS matching operation may further comprise the steps:
(a) described resolver is sent to described domain name coupling add-on module with this domain name mapping request;
(b) this domain name coupling add-on module is inquired about in the domain name matching database according to this domain name, and this inquiry may further comprise the steps:
(i) domain name coupling add-on module takes out similar or several domain names of domain name in all and the described domain name mapping request, and described domain name is similar to be meant that a domain name character string is the prefix of another domain name character string, infix or suffix;
(ii) domain name coupling add-on module obtains or several IP addresses of its correspondence according to one of above-mentioned taking-up or several domain names;
(c) this domain name coupling add-on module a series of IP address that will inquire as a result of returns to described resolver;
(7) this resolver returns to client with the result of DNS matching operation as replying;
(8) client is carried out corresponding navigation process operation according to replying of returning of resolver, and this navigation process operation may further comprise the steps:
(a) if this replying of returning is unique IP address, then client is directly carried out the browse request operation at this IP address;
(b) if this return reply address for a plurality of IP, then client is listed this all IP address;
(c) client is selected unique IP address according to user's selection operation, the browse request operation of the hand-manipulating of needle to the IP address of this selection of going forward side by side.
In practical operation, for the incomplete domain name of user in browser client input, resolver is according to the keyword of domain name, the similar results of foldback user related keyword, and the user can choose the IP address of oneself wanting.Its specific implementation method is: additional functional module in existing browser network element structure, this module mainly comprises the database of a continual renovation, when this module is inquired, it with foldback to all similar results of resolver.In the DNS query script, when being provided by the DNS that inquired when replying, resolver will turn to the additional functional module of inquiry, and resolver will obtain and the relevant a series of IP address of inquire about, and the user is the required IP of selection therein oneself only.When module was inquired, it returned foldback to all similar results of resolver, and the user therefrom chooses the IP address of oneself wanting.
Adopted the method for above-mentioned searching internetwork address on computer, because for infull domain name, the keyword of the domain name that resolver is imported in client according to the user, the similar results of foldback user related keyword, the IP address that makes the user to choose oneself to want is carried out searching internetwork address to the user and is brought great convenience.
In this specification, the present invention is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
