root.cache --
file format containing names of root domain servers
Format

nameserver2 ttl class NS address
Description
The root.cache
file primes the name server's cache with the addresses
of the authoritative name servers for the root domain of the
network. The location of this file is specified in the
file substatement of the ``.'' zone statement
in /etc/named.conf.
It is available via anonymous FTP from RS.INTERNIC.NET
as /domain/named.root. Because the contents of this file change
periodically, you should retrieve it regularly to ensure that you
have the current version.
ttl should be a large number, such as 99999999, so that the
local ttl will expire sooner and it will not be
necessary to refer to this file continuously.
