# Sample lookup procedure for tcldb
|
|
#
|
|
# This lookup procedure defines zones with identical SOA, NS, and MX
|
|
# records at the apex and a single A record that varies from zone to
|
|
# zone at the name "www".
|
|
#
|
|
# Something like this could be used by a web hosting company to serve
|
|
# a number of domains without needing to create a separate master file
|
|
# for each domain. Instead, all per-zone data (in this case, a single
|
|
# IP address) specified in the named.conf file like this:
|
|
#
|
|
# zone "a.com." { type master; database "tcl 10.0.0.42"; };
|
|
# zone "b.com." { type master; database "tcl 10.0.0.99"; };
|
|
#
|
|
# Since the tcldb driver doesn't support zone transfers, there should
|
|
# be at least two identically configured master servers. In the
|
|
# example below, they are assumed to be called ns1.isp.nil and
|
|
# ns2.isp.nil.
|
|
