3G / GPRS uses shared IP addresses. Please be good on IRC.

I always wondered if this was the case .. trying to log into Blabbernet IRC server I disconnected before because of "too many connections from same IP" before, and this time :

Closing Link: mynick[196.xxx.yy.zz] (User has been banned from BlabberNet (Autokilled: idiot)).

I emailed the server staff, and later receice reply:

You use GPRS to connect.

GPRS uses shared IP addresses.

A ban intended for another user therefore affected you.

It has subsequently been removed. Please reconnect.

You can always ask for the internetvpn apn and connect from there. I have just mailed the IRCOPS and asked them to increase the limits, they normally helpfull

Laterz !!!

EDIT: But yes - point taken - so guys and gals - be good !

Anybody that still blocks individual users based on IP address deserves to be shot. It has nothing to do with GPRS or 3G. GPRS and 3G uses NAT and you are assigned a private IP address which goes through a gateway with a single public address. This technology is used in a number of other networks as well - company networks, Internet Connection Sharing, mesh networks and some WiFi access points.

I suggest that you e-mail the admin and ask him to remove this functionality - it is useless anyway. You cannot block shared addresses, and users with public addresses normally doesn't have fixed public addresses - they are assigned from the ISP's pool and the subscribers share the pool, meaning people on the same ISP can get blocked because another subscriber abused the service. For the last mentioned case, all the offender have to do is reconnect to obtain a different IP address.

So IP filtering is useless. You'll only stop people with fixed IP addresses which is by far the minority and normally not the people who abuse the service in the first place.
