Random, blocks, certain durations, etc. Its very random and or short lived which is something we don't want to move to the firewall at the moment

When I do have to manage IP lists in Nginx I try to compress the lists into the most compact CIDR representation so there is less to search. Here is a perl snippet I use to do that (handles ipv4 and ipv6): #!/usr/bin/perl use NetAddr::IP; my @addresses; foreach my $subnet (split(/\s+/, $list_of_ips)) { push(@addresses, NetAddr::IP->new($subnet)); } foreach my $cidr (NetAddr::IP::compact(@addresses)) { if ($cidr->version == 4) { print $cidr .
