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.
