I am banning people by ip. But won't their ip change at some point so banning is useless? How do I know I am not banning Comcast server itself instead of a user. What is the ip address I was given is shared among a group of comcast users. I will have just blocked a lot of people, not just the one I wanted. The ip's causing me trouble are 166.137.136.247 166.205.14.131 69.115.146.224 86.131.255.105 Is there a way to tell if it is just a single person ip or a big network ip?
the rule of thumb is do not block unless you have to, and if you have blocked it - don't worry about it another words - who care if you also (accidentally) blocked somebody else on the same IP, but do not block unnecessarily so you would minimize that chance
