Bind zones can handle wildcard

[sudhaker]

Unlike host file, bind can handle wildcard so why don't we optimize the zone file for domains?

For example

$ cat adblock.rpz | wc -l
134973 (total lines)

$ grep .302br.net adblock.rpz | wc -l
17943
$ grep .hpg.com.br adblock.rpz | wc -l
878

Replacing these entries with followings will make things smaller, faster & much efficient.

*.302br.net IN CNAME . *.hpg.com.br IN CNAME .

seems great, but how to automate it? you don't want to search for domains to be simplified by wildcards in the list manually.

also not all are due to be shortened via wildcards, as you might block to much

Combining entries will probably lead to overblocking. Because of that I don't plan to add it.
