Abstract

The present invention provides a new and improved domain name searching method and system which comprises steps selected from the group consisting of (1) downloading all zone files, public and/or non-public, associated with one or more host names; (2) performing reverse DNS on IPs associated with said host names in associated root servers and name servers; (3) crawling websites associated with said host names and seeking new hosts on known websites in different TLDs; (4) indexing all new host names found; (5) resolving the associated IP address with each host name, and with optionally appending “www” thereby; (6) storing DNS entries and indexing same while logging their association with host names; (7) repeating any of steps (1) through (6) one or more times.

Claims

1. A method for searching domain names comprising the steps selected from the group consisting of:

(a) downloading one or more zone files associated with one or more domain names;

(b) performing reverse DNS on said domain names in associated root servers and name servers;

(c) crawling websites associated with said host names and seeking new hosts on known websites in different TLDs;

(d) indexing all new host names found;

(e) resolving the associated IP address with each host name'"'"'

(f) repeating any of steps (b), (c), (d), and (e) one or more times.

2. The method of claim 1 further comprising the step of storing DNS entries while logging an entries association with a host name.

3. The method of claim 1 wherein step (a) is conducted in public and non-public zone files.

4. The method of claim 1 further comprising generating a result of the search.

5. The method of claim 1 further comprising a step of searching MX records, IP addresses therefrom, and performing reverse DNS, and optionally forward DNS, thereon.

6. The method of claim 5 further comprising generating a result of the search.

7. The method of claims 1 and 5 wherein the results of the search form a baseline database.

8. The method of claims 1 and 5 which are performed a plurality of times, the results of which are compared with a baseline database.

9. A method of conducting a business comprising activities selected from the group consisting of manufacturing, having manufactured, advertising, offering for sale, selling, distributing and licensing a domain name searching method andor system of claims 1, 2, 3, 4, 5, 6, 7, and 8.
