There are vanity vhosts and there are cloaks.

Cloaks apply uniformally but will not mask the last bit of your reversed hostname. So it might leak info about your ISP or region but not your full IP.

What you stated is true of vanity vhosts though. Which will mask the whole record only if you’re logged in. :)

I think this is a split in terminology, actually.

IRCds such as InspIRCd and UnrealIRCd speak of cloaks in the sense of user mode +x, commonly set on connection, which scrambles an incoming user's hostname/IP address to e.g. hidden-5npgt1.iinet.net.au or hidden-qjia2j.ncp0.j4h4.014d.2804.IP.

Freenode, nota bene the largest IRC network right now, uses cloaks to instead refers to a special format of vHost[1]. It does not offer Unreal-style cloaking.

I imagine this difference in terminology is what's prompted this exchange.

Back in the days I had to pay extra for a bnc/bouncer service (similar to a proxy), now most IRC networks offer vhost automatically, but I assume it's a bit less secured since the IRC networks themselves still know your real IP address.

It's not really possible for a server not to know the clients IP address though, so I think this is fair.

I do see what IP you're connecting from, but that information is limited to me only, and it's not like I care unless you're doing something very harmful to the service in which case I would ban you based on IP most likely.
