The label database has one entry per line. Each entry has three fields separated by white space: an IP number, a label, and the date (as yyyymmdd) it was collected.
The label consists of a name as returned by a DNS PTR lookup. If a domain nameserver reported ``no such domain,'' the domain of that nameserver is given in parenthesis. This gives some idea of who owns the IP address. If there is no answer, the label is the IP number enclosed in less-than/greater-than symbols: <188.8.131.52>.
