How does a board owner know when an IP is dynamic?
Some ISPs have their ranges listed, but some don’t. You can tell who has a dynamic IP on the board. When the board owner looks up a profile and looks at the IPs used by this profile, if the member has been to the board several times, they will most likely show multiple IPs, this is an indication that their IP is dynamic. If the member has been to the board on several occasions and there is only 1 IP showing, it means that the IP is static. In such cases – and only in such cases- an IP ban can be effective.
