Hey, when blockimg an IP address, (unlike an account) understand ips change quite often, and good users caneasily end up under those IPs later. Meanwhile, the bad users you meant to block, will later end under different IPs, which is why it's generally not good to block anonymous IP addresses permanently.

Generally, 3 momths is standard and ideal for an anon IP block, by that time the trolls will almost certainly be under a different IP.

(This is of course different from blocking an account username, as that is a single person, and permanent block are fine then.
