Organization IP address is getting redirected to a website which does not belong to the organization.

Hi Sandeep,

The redirect part isn't a DNS issue: I telnetted to port 80 on the IP
address and got:

john at millspad:~$ telnet 146.142.7.113 80
Trying 146.142.7.113...
Connected to 146.142.7.113.
Escape character is '^]'.

Connection closed by foreign host.

But something is definitely listening on that IP address.  Could be a
rogue device or some sort of routing issue.  Here's a traceroute from
the Brandeis network:

That's one convoluted route to stay in the same /24!  I'd have a chat
with your network admins and see what's up--this doesn't look normal.

Question for you: how'd you uncover the issue?  Do any DNS records
point to 146.142.7.113?  There's no reverse record for it that I can
see.
