Suspicious forum notifications/ website

I got an email notification of topic reply which asked me to log in when I clicked the link. I did so and it took me to the forum. However shortly afterward I noticed the actual address was shown as IP address in the URL bar, not "forums.debian.net" as usual. Is this suspicious?
The address is http://217.196.43.138/viewtopic.php?f=7&t=12131.... etc.

It resolves to
IP Address : 217.196.43.138
Location : Netherlands (95% accuracy)
Host Name : tartini.debian.net
whereas debian.net is
Host Name : debian.net
IP Address : 5.153.231.4 and 128.31.0.62 and 130.89.148.14 and 140.211.15.34 and 149.20.20.22
Location : United States
I guess it's just a mirror but just wondering why it doesn't resolve the IP address. Another topic notification email I got at the same time resolved normally.

I hope you didn't login, ?


Well one thing, there has been no replies since 2007, :

Here is the real thread on this forum :
http://forums.debian.net/viewtopic.php?f=5&t=12131
And there have been no recent posts to it.
Is this suspicious?
To me it is, but maybe some of the forum admins know more about this.

Nope. That's the correct IP address.

Code: Select all

$dig forums.debian.net

; <<>> DiG 9.8.4-rpz2+rl005.12-P1 <<>> forums.debian.net
[snip]

;; ANSWER SECTION:
forums.debian.net.      3246    IN      A       217.196.43.138
The forums are hosted on their own server, whose name is indeed tartini (and has been for as long as I can remember):

Code: Select all

$ dig  -x 217.196.43.138

; <<>> DiG 9.8.4-rpz2+rl005.12-P1 <<>> -x 217.196.43.138

;; ANSWER SECTION:
138.43.196.217.in-addr.arpa. 27703 IN   PTR     tartini.debian.net.
I'm not 100% sure of the country in which tartini resides, though I have a very strong recollection of it being somewhere in the general area of northwest Europe.

Good catch, though. :cool: Better safe, and all that.

Edit: Downgraded what sounded like firsthand knowledge to something slightly less certain.

I thought it was probably legit after doing lookups, but worth a mention. Wondering more why it didn't resolve to hostname as it always had in the past.

Absolutely.

DNS gremlins, mebbe. Or possible browser bug. Invisible Pink Unicorns possible, but unproved.
