impersonator on emule

[Debaser]

Like I know what that means

[emuler]

It means that he has blocked 65536 IP addresses. This is overkill. You find one or two bad clients and you nuke an entire range.

[FLL]

And it's worse than that, the cable company in Poland which has that IP only has half the range, the top half (62.21.128.0 to 62.21.255.255) is actually in the Netherlands.

whois shows that 62.21.112.0 - 62.21.118.255 is a single allocated block, only 1792 IPs. If you want to block the guy that range will probably do it (though you can't know for sure how that cable company assigns addresses).

[emuler]

True. Most ISPs don't get to choose; they take whatever block of IPs is available. Mine has several non-contiguous ranges, so my IP can change drastically depending on the block from which the ISP hands one out to me. When they got a new block of IPs assigned, my IP was in the ipfilter for a couple of days before the guys who make the ipfilter relaized that a formerly unaloocated block was now in use and fixed it.

I reckon this is just one of those annoying "live with it" things as - only if this person has a fixed IP - not so common in this day and age, or vitually never closed his/her broadband down, are you going to find that the IP address you blocked is the correct one. I agree with EMuler/FLL that blocking that RANGE fro the iSP may be the way to go, but even that is not vertain to do the job.

[Debaser]

Hang on. I didnt add the range, just the one IP 62.21.118.212

Why would I add the whole range?

[billanben]

I'm sick of this so from now on I'll be posting the IP addresses of these leechers here, first one:

62.21.118.212

From Poland, added range to IP filter: 62.21.0.0-62.21.255.255

And you said - good idea - I'll add that to my firewall - now I wasn't the only one who thought the same DB

[Debaser]

Sorry, didnt meen to sound short.

Im not an IP expert by any means!

Because these days many people get assigned a different IP by their ISP every time they reconnect, dynamically picked from the pool of IP addresses the ISP has available. As long as your cable or DSL modem or router stays connected you keep the same address, but power cycle it and your IP will probably change. If someone who is blocked by IP address knows this, they will try to get around the block by getting a different IP address.

To keep your block effective you need to block the entire range of addresses the miscreant might get. The problem is in figuring out what that range is, there's no easy way to know what addresses their ISP has available or how they assign them. Plus the bigger the range you block you also block lots of other people you don't intend to block and who are potential sources. So as a first try you should probably just block one IP and hope he doesn't change it, then as a next step block a small range, then larger ones if that doesn't work. Of course it all depends how much it bothers you whether it's worth the effort or not.

[emuler]

But why block him at all? OK he's a little irritating, but what's new about that - everyone irritates someone at one time or another. He's not doing any real harm, not like he's spreading corruption or anything. If he (mistakenly) feels that doing so will improve his eMule experience, let him clone nicks till he's blue in the face.
