For example, the following DLZ configuration would match +any zone name containing the string "example" and ending with .com, such +as "thisexample.com", "exampleofthat.com", or "anexampleoftheotherthing.com". + + dlz "test" { + database "dlopen ../dlz_wildcard_dynamic.so + *example*.com 10.53.* 1800 + @ 3600 SOA {ns3.example.nil. support.example.nil. 42 14400 7200 2592000 600} + @ 3600 NS ns3.example.nil. + @ 3600 NS ns4.example.nil. + @ 3600 NS ns8.example.nil. + @ 3600 MX {5 mail.example.nil.} + ftp 86400 A 192.0.0.1 + sql 86400 A 192.0.0.2 + tmp {} A 192.0.0.3 + www 86400 A 192.0.0.3 + www 86400 AAAA ::1 + txt 300 TXT {\"you requested $record$ in $zone$\"} + * 86400 A 192.0.0.100"; + }; + +For any zone name matching the wildcard, it would return the data from +the template. "$zone$" is replaced with zone name: i.e., the shortest +possible string of labels in the query name that matches the wildcard. +"$record$" is replaced with the remainder of the query name. In the +example above, a query for "txt.thisexample.com/TXT" would return the +string "you requested txt in thisexample.com". + +Any client whose source address matches the second wildcard ("10.53.*") +is allowed to request a zone transfer. |
