After seeing some shenanigans tonight with an errant connection, here is a fairly easy and quick way to block a specific IP address for good. Assuming windows firewall is on and running (it is by default), the at an elevated command line run: netsh advfirewall firewall add rule name="IP Block" dir=in interface=any action=block remoteip=<put dodgy IP here>/32 To get an elevated command line, press start, type cmd, and then right click on cmd.exe and select run as administrator.

I have no idea what this post is in response to (I assume it is a multiplayer issue), but I would just add that once the session has finished I would delete that rule again. Most computers connect to the Internet via DHCP, so their IP address gets recycled periodically. Thus, the offending connection will almost certainly have a new IP address within 24 hours (if not before), and leaving the rule in place could (very small chance, admittedly) coincidentally block someone else that happens to be given that IP address in the future.

To put it into context, last night's hosted game was aborted twice because of a port probe attack on the host's IP address and port. There was a line of thought that this was deliberately targeted from the details in the forum. It would be very unlikely that the errant IP address is then legitimately allocated to a genuine user, however if you are one for tidying up, the rule can be deleted with netsh advfirewall firewall delete rule name="IP Block" dir=in remoteip=<dodgy IP>/32 Log in to reply |

I'm also getting IP address by DHCP and my IP address hasn't changed in years. It works for other people hosting, too (so you can guess their IP address beforehand). In fact, it's the sanest thing the ISP could do. Log in to reply |

" said:" said:Yes, it'll vary. But the statement that "most computers' ... address gets recycled periodically" is simply wrong, at least in the context of home users (doesn't pertain to mobile or dial-up). It's also the most logical thing to happen. The impression that "DHCP addresses are almost next to random" is simply unfounded." said:It'll vary by ISP as to when; or if you ever, get given a new IP address.

Well, good for you! However, it is totally irrelevant - I don't pay for any such thing. And yes, my ISP offers it as well. Not to mention that the "offending" IP in question was actually a server, whose address, as witnessed by Google searches, hasn't also changed in years. And that calling sending a few packets (3) "attack" is a bit of making a storm in a teapot. Log in to reply |

In my personal experience my IP address (well, the router’s IP address) got recycled fairly regularly and I must’ve extrapolated that too far. Log in to reply |

In reguards to changing IP's I think that those who use telephone based broadband (ie: in the uk it is provided mainly by BT phonelines, reguardless who the service provider is talk talk, sky etc ) they are the ones that tend to change more often. As I use cable (virgin media) and I have found that I tend to keep the same IP for very long periods of time. If a user uses mobile broadband or a wifi hotspot then in almost all cases the IP will be different every time. Although that doesn't take into account people using IP masking techniques.
