automatic reverse and forwarding zones

[JAHANZAIB SYED]

It can be done on a need/manual basis, or if you have large ip block & you want to reply automatically created response for your ip's , you can use $GENERATE statement.

Basic example of adding auto PTR/REVERSE ipv4 Record generation

Edit the corresponding REVERSE zone & add following line in the end

$GENERATE 1-255 $ IN PTR 10-11-11-$.example.com.

Dont forget to Reload bind config & you are done.

Subject: automatic reverse and forwarding zones

Hello,

how do ISPs automatically create the reverse and forwaring zones for
their customers IP pools?

For example one of their clients has the IP 2001:db::3.

Its reverse zone
3.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.b.d.0.0.1.0.0.2.ip6.arpa
includes a PTR pointing to
3.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.b.d.0.0.1.0.0.2.isp.example.org

This has an AAAA record of 2001:db::3.

Is it possible to let bind create that automatically for certain zones?
