No IP address for a registered user?

[SulevFan]

I have a user that has registered and posted, yet there is no IP address associated with his userid. How is this possible?

[busterone]

Has this user posted as a potential contributing member, or does it smell like spam? I have seen badly configured spambots attempting to mask their IP and useragent  to cause smf to list the IP as 127.0.0.1, but never a blank before.

He posted relevant content to the forum and the thread.

I've seen someone register with no visible IP address and another who had no visible e-mail address. There is software you can get which will do this but I'd treat this member with considerable caution.

Deleting his account should be easy enough but banning his IP would be very difficult because you don't know what it is.


Edit : I've had a message from a guy who seriously knows what he's talking about...If a user visits the forum through an IPv6 connection, SMF will ignore it and empty it out. This is happening more and more...

[busterone]

Yep, I just realized after reading it that an IPv6 could be the reason.

[SulevFan]

Now if it was a spammer, then what? What's going to happen with IPV6 addresses?

[busterone]

That is a good question. Even once SMF has complete IPv6 compatibility, the possibility of endless ip's in the spammers' arsenal, we will take a hard shot.
The current blocking techniques will suddenly change in their favor, not ours.

Sometimes IP resolving simply fails without any specific reason too, although v6 will also make a challenge like already mentioned as current SMF versions don't support v6.

hmm, it could be that he uses an ip-changer-like program...

[Aleksi "Lex" Kilpinen]

Unlikely, as that would actually change the IP - not cause it to fail completely

i don't think that somebody got no ip, so it could be over an ip-hiding program?
i'm not that good in programming such things :S (VB, C#, C++...)
