IP-Address without Network Interface installed

[Lukas Ruf <ruf_(_at_)_tik_(_dot_)_ee_(_dot_)_ethz_(_dot_)_ch>]

Dear List,

1st: is it possible to have OpenBSD 2.5 configured for a special IP-Address
even if the normaly connected Network Interface Card (I use a Laptop) is
removed?

2nd: when I recently installed OpenBSD 2.5 on my laptop I noticed the
beg to send some message to any address; I suppose it was dmesg | mail ?
If you could tell me which address and which message, I would like to
transmit this information.

Thanks in advance.

Kind regards,

Lukas
