No, because you need to configure the servers interfaces somehow ! 
You cannot reasonably configure them from a DHCP service running on 
the same server and so they should be statically configured.

Creating a host declaration as shown will simply prevent the server 
handing out a lease - it won't stop the client asking for one, or 
complaining when it gets no response.

What do you mean by "... keeps telling that it has no wired network 
..." ? Is this in the logs (which logs ? what process name ?) or 
somewhere else ?

"dhcpd if1" is not a valid statement for the dhcpd.conf file. It's 
something that is passed via the command line, so is either part of 
the command file that loads the dhcp service, or a config file read 
by it.
