hosts-entry... wtf?!

[Sven Burgener]

Hi all

For some weird reason, I have the following entry in my /etc/hosts file.
What is the meaning of that? I dont think I added it myself... ! (I
changed the real FQDN)

0.0.0.0                host.domain.com

This doesn't feel good...

TIA
Sven (CC me, please)
