IP display in ICQ profiles: How is this possible?

In the original ICQ application for the Mac OS and AFAIK also in the PC version the IP address of your online contacts could never be seen. I thought the ICQ client was only provided the IP address of a contact if a file transfer attempt was made which required a direct socket connection. Now with Adium I can see the IP address of any online ICQ contact (not a very comforting thought that your IP address is distributed to all your online contacts). How is this possible?

The server needs to see it to download/upload to the computer.

And so does the client.

As far as I've ever known, PC users of ICQ could always see your IP address, and it was just the general godawfulosity of the Mac version (Thanks, Miribalis, really. "Oh, 'Next Message' causes a catastrophic crash of the program 100% of the time and almost brings the whole computer down with it? Let's leave that version up for FOUR YEARS") that it didn't have a likewise feature.

The windows version (used to? back when I used it last.. decade) showed the self-reported IP. It's client-based, I believe. Hardly an authority on IP, since I'd always see 192.168.0.0/16 addresses.

Whoa.. you saw you wire adress and subnet? Or did you set your routher to allow a x.x.x.0 to be a host adress?

"xxx.xxx.xxx.xxx/dd" is standard notation to denote a range of IPs. the first "xxx" is /8, second "xxx" is /16, etc. There's also different ones inbetween to denote other ranges, such as /20 or something. xxx.xxx.xxx.0 is a valid IP in certain ranges, depending on the router IP and such.
