Method and apparatus for providing name services
View Patent ↗An embodiment of the invention comprises a method and apparatus for providing dynamic name resolution services based on information stored and served in a root server. A multi-part reference to the name resolution server is stored on the root servers. By analyzing the reference to the name resolution server, the name resolution server is capable of dynamically generating a canonical name associated with a domain and/or a host name. The domain and/or host name may be further examined by network resource servers to determine further information about a requested resource.
1. A method performed in a first name server, the method comprising:
sending, to a second name server, a name resolution query for a resource, the resource comprising a first domain name;
receiving a reply to the query, the reply comprising a multi-part textual reference associated with the first name server, wherein said multipart textual reference comprises at least the first domain name, second domain name, and a resource location reference;
dynamically generating a multi-part canonical name from said multi-part textual reference, said multi-part canonical name comprising the second domain name and the resource location reference; and
resolving said canonical name into a numerical address.
2. The method in claim 1 wherein said multi-part textual reference further comprises at least two dot-separated text strings.
3. The method in claim 1 wherein said multi-part textual reference complies with a Internet Protocol naming standard.
4. The method in claim 1 wherein said obtaining said multi-part textual reference further comprises making a request to a root domain name server to resolve a domain name.
5. The method in claim 1 wherein said first host domain name appears as a sub-domain in said multi-part textual reference.
6. The method in claim 1 wherein said first resource location reference further comprises at least one text string.
7. The method in claim 1 wherein said first host domain reference and said second host domain reference are identical.
8. The method in claim 1 wherein said first host domain reference and said second host domain reference are different.
9. The method in claim 1 wherein said first resource location reference and said second resource location reference are identical.
10. The method in claim 1 wherein said first resource location reference and said second resource location reference are different.
11. A method, performed by a hosting service having a first domain name, comprising:
receiving a second domain name, different than the first domain name, and a resource storage location;
generating a textual name server reference based on the second domain name and the resource storage location, the textual name server reference comprising at least two parts, wherein said at least two parts comprises a first part corresponding to the resource storage location, and a second part corresponding to the first domain name; and
registering the second domain name and a numerical address of a name server for the hosting service, in association with the textual name server reference, with a central authority.
12. The method in claim 11 wherein said textual reference further comprises a third part indicating a registered domain name.
13. The method in claim 11 wherein said textual reference further comprises a reference to a domain name resolution server.
14. The method in claim 11 wherein said textual reference further comprises a multi-string dot-separated text reference.
15. The method in claim 14 wherein said multi-string dot separated text reference complies with Internet Protocol standards.
16. In a network environment, a method for providing name resolution services comprising:
registering a textual reference and a numerical address with a central authority in association with a first domain name, the textual reference comprising a first part and a second part, the first part indicating a network resource location, the second part indicating a hosting domain name different than the first domain name;
obtaining said textual reference in reply to a query to a name resolution server;
dynamically generating a multi-part canonical name from said multi-part textual reference, said multi-part canonical name comprising the network resource location and the hosting domain name;
resolving said canonical name into a numerical address;
receiving a request for a resource located on a resource server, wherein said request comprises access to said resource on said first domain name;
obtaining said multi-part canonical name; and
obtaining an access resource location to said resource by parsing said dynamically generated multi-part canonical name.
17. A method performed in a first name server located in a hosting network, the method comprising the steps of:
receiving a name resolution query for a resource server;
sending the name resolution query to a second name server;
receiving a reply from the second name server, the reply comprising a multi-part textual reference associated with the first name server;
parsing the multi-part textual reference into a distinct first, a second, and third part, the first part corresponding to the resource server, the second part naming a domain, and the third part identifying a resource location within the hosting network; and
generating a multi-part canonical name containing second part and the third part.
18. The method of claim 17 , wherein the second name server is a root name server.
19. The method of claim 17 , wherein the multi-part canonical name does not contain the first part.
20. The method of claim 17 , wherein the domain named in the second part of the multi-part textual reference is different than the domain of the resource server in the name resolution query.
21. The method of claim 17 , further comprising the step of:
resolving the canonical name into a numerical address.
22. The method of claim 21 , further comprising the step of:
replying to the name resolution query with the resolved numerical address.
23. The method of claim 17 , further comprising the step of:
receiving a name resolution query for a resource server located in the hosting network.
24. The method of claim 23 , wherein the first part corresponds to the resource server, the second part corresponds to the domain name of the hosting network, and the third part identifies a resource location within the hosting network.
25. The method of claim 1 , wherein the multi-part textual reference identifies the first name server.
26. The method of claim 1 , wherein the multi-part textual reference is associated with the first name server through a registration of the first name server as a name server for the resource server.
27. The method of claim 1 , wherein the multi-part textual reference is associated with the first name server through a registration of the first name server as an authoritative name server for the resource server.
