I've bolded the the part of your statement that makes literally no sense. Like, it's completely nonsensical. Like, there is literally nothing right about the use of any of those words in that sentence.
If you have a static IP, your IP stays the same, always. You can manually release your WAN IP, but that is not where traffic is directed to. Your internet address does not change if you have a static IP. Lets say you have a dynamic IP. It would change more often than once in your entire history of playing on this server, therefore there would be several IPs used to connect to the server under your steam ID. As far as I know (as it hasn't been brought up, that's not the case). Furthermore, presuming under the ideal conditions that you have a dynamic IP address, that only changed once when you released it, and somebody out there liked to use hacks and decided to release their dynamic IP at the same time, and lived in your general area, as came onto the server that you regularily played on, and hacked and got banned, the chances of you ending up with the original IP address at the end of this is probably lower than the chance of CiNiC making me the best man at his wedding.
Do we need to try again?
