This is not good idea to use statefull firewall on heavy loaded DNS server. firewall becomes low place in the system. As workaround you can use dns_flood_detector + simple script to insert and remove IP's from firewall blocking table or chain. 27.10.2010 23:26, Sebastian Tymków пишет: > In FreeBS

PTR RRs benefit from label compression, whereas TXT records do not. Therefore I prefer PTR records for any such "metadata" references within DNS. There's no chance they'll be mistaken for, or conflict with reverse DNS records if they're not in the in-addr.arpa branch of the namespace.
