7 REVERSE(127.0.0, localhost)
9 ; A pretty normal example domain (we act as a primary nameserver for it)
13 ; It also has a couple of sub-domains and one of them resides on another server
15 PRIMARY(a.example.com)
16 SECONDARY(b.example.com, 10.0.0.1)
18 ; Yet another subdomain residing on another server, but this time with
19 ; access restricted to the internal network. The closing quote after the
20 ; options has to be on a separate line, because semicolon is a comment character.

30 ; the PTR records from A records in all mentioned zones. See cf/{0,1}.0.10.
32 REVERSE(10.0.0, example.com, a.example.com)
33 REVERSE(10.1.0, example.com, a.example.com, ip6.example.com)
35 ; You can even have reverse zones for larger networks
37 REVERSE(10.2, a.example.com)
39 ; Here are the examples of classless reverse delegation using subdomains
40 ; and PTR records as recommended by RFC 2317. We use the subdomain names
41 ; recommended by the RFC, however, this is not fixed anywhere and you can
42 ; use any names you like (or your ISP likes).
44 ; In the 10.1.0 network, we define a classless delegation (see cf/0.1.10),
45 ; but we also want to run a secondary server for the subdomain. As usually,
46 ; the REV macro is handy for constructing a reverse domain name.
48 SECONDARY(REV(10.1.0.128/25), 10.1.0.2)
50 ; And vice versa: we are delegated 10.3.0.64/26, so we want to create
51 ; the corresponding subdomain. The "/" in domain name gets automatically
52 ; translated to "@" when forming a file name, so you will find the corresponding
53 ; config file in cf/64@26.0.3.10.
55 REVERSE(10.3.0.64/26, a.example.com)
57 ; The final challenge: a subdomain with both IPv4 and IPv6 records
58 ; together with the corresponding reverse records (in IPv6 mode, all
59 ; networks are always accompanied by a netmask).
