Abstract

A secure domain name service for a computer network is disclosed that includes a portal connected to a computer network, such as the Internet, and a domain name database connected to the computer network through the portal. The portal authenticates a query for a secure computer network address, and the domain name database stores secure computer network addresses for the computer network. Each secure computer network address is based on a non-standard top-level domain name, such as .scom, .sorg, .snet, .snet, .sedu, .smil and .sint.

Claims

1. A computer-readable storage medium, comprising:

a storage area; and

computer-readable instructions for a method for registering a secure domain name, the method comprising steps of;

receiving a request for registering a secure domain name;

verifying ownership information for an equivalent non-secure domain name corresponding to the secure domain name;

registering the secure domain name in a secure domain name service when the ownership information for the equivalent non-secure domain name is consistent with ownership information for the secure domain name.

2. The computer-readable medium according to claim 1, wherein the step of verifying ownership information includes steps of:

determining whether the equivalent non-secure domain name corresponding to the secure domain name has been registered in a non-secure domain name service; and

querying whether the equivalent non-secure domain name should be registered in the non-secure domain name service when the equivalent non-secure domain name has not been registered in the non-secure domain name service.

3. A method for registering a domain name, comprising steps of:

(i) receiving a request for registering a first domain name;

(ii) verifying ownership information for a second domain name corresponding to the first domain name; and

(ii) registering the first domain name when the ownership information for the second domain name is consistent with ownership information for the first domain name.

4. The method of claim 3, wherein the first domain name comprises a non-standard top-level domain and the second domain name comprises a standard top-level domain.

5. The method of claim 3, further comprising the step of storing information corresponding to the registration performed in step (iii) in a database separate from a database storing information for standard domain name registrations.

6. The method according to claim 3, wherein the step of verifying ownership information includes steps of:

determining whether the second domain name has been registered in a domain name service; and

querying whether the second domain name should be registered in the domain name service when the second domain name has not been registered in the domain name service.

7. The method of claim 6, wherein the first domain name is a secure domain name.

8. The method of claim 7, wherein the first domain name is registered in a secure domain name service.

9. The method of claim 7, wherein the secure domain name has a top-level domain reserved for secure network connections.

10. The computer-readable storage medium of claim 7, wherein the secure domain name has a top-level domain reserved from secure network connections.

11. A computer-readable medium, comprising computer-readable instructions for a method for registering a domain name, the method comprising steps of:

receiving a request for registering a first domain name;

verifying ownership information for a second domain name corresponding to the first domain name; and

registering the first domain name when the ownership information for the second domain name is consistent with ownership information for the first domain name.

12. The computer readable medium of claim 11, wherein the first domain name comprises a non-standard top-level domain and the second domain name comprises a standard top-level domain.

13. The computer-readable medium of claim 11, wherein the step of verifying ownership information includes steps of:

determining whether the second domain name has been registered in a domain name service; and

querying whether the second domain name should be registered in the domain name service when the second domain name has not been registered in the domain name service.
