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 system for providing a secure domain name service over a computer network, comprising:

a portal connected to a computer network, the portal authenticating a query for a secure computer network address; and

a domain name database connected to the computer network through the portal, the domain name database storing secure computer network addresses for the computer network.

2. An apparatus configured to query a computer network address having a top level domain reserved for secure network connections.

3. A method comprising querying a computer network address having a top-level domain reserved for secure network connections.
