[b]"How Do I Block an IP Address Effectively?"[/b] or [b]"What’s the Best Way to Block an IP from Accessing My Net

Blocking an IP on a router doesn’t always stop everything. Some traffic might slip through if the router’s firmware is outdated. Have you checked for updates?

Also, if the IP is changing (like with a VPN), blocking one won’t help. You might need to block a range or use a dynamic DNS blocker.

Tools like PeerBlock can help on the PC side if the router fails.
