DNS Problems and 127.0.0.2 Address

20/04/2010 - 01:33 von Joseph Morales | Report spam
We're experimenting with deploying SUSE 10 SP3 systems and adding them to a
Windows domain and DNS. Oddly, when we register in DNS, it gets registered
under two address: the real IP address, and the address 127.0.0.2. Also, an
ip addr command shows that the loopback device lo has two addresses:
127.0.0.1 and 127.0.0.2.

The above behavior is just on SP3. On SUSE 10 SP2, the lo device has only
the 127.0.0.1 address, and the system is able to register correctly in DNS.

Has anyone ever seen this behavior? Do you know what the 127.0.0.2 address
signifies, or how to get rid of it?

Thanks, Joseph

Don't know anything abuse SUSE.

The only time I've heard of 127.0.0.2 is in the context of email block
lists such as spamcop. You lookup a sender IP in their DNS and they return
127.0.0.2 if it's a spammer.
