Palage United States Patent 6,745,248 Gardos , et al. June 1, 2004 -- Method and apparatus for analyzing domain name registrations Abstract Downloading an authoritative zone file and performing searches within the zone file can identify all of the domain names registered to an entity. A method of identifying all of the domain names registered to an entity may including downloading a root zone file from a registry or from a root server and storing the root zone file as a text file with alphanumeric character strings associating each domain name with a registrar and at least one domain name server. A search characteristic is established corresponding to a character string comprising a significant part of one of the entity's domain names. A string search is performed in the download root zone file for the search characteristic to identify one or more domain names matching the search characteristic, as well as a registrar corresponding to the matching domain name and at least one domain name server associated with the matching domain name in the downloaded root zone file. Each matching domain name is stored in a data file, so that the data file associates each extracted domain name with the corresponding registrar and the at least one domain name server. The method continues by repeating, at least once, the successive processes of establishing a second search characteristic, extracting from the registry at least one additional domain name on the basis of the second search characteristic and storing each additional matching domain name in the data file. ---------------------------------------------------------------------------- ---- Inventors: Gardos; Robert D.
