Whatever you want. For maximum consistency, don't hesitate
to create the corresponding entries for your hostname in
/etc/hosts, for example:

	127.0.0.1	localhost
	127.0.0.1	fqdn.example.com
	123.45.678.90	fqdn.example.com

Of course, a part of this can be donw with with DHCP.

Definitely, and probably the router won't let you configure
those things at the level required. Maybe you can replace
that unit with a more generic one, with more powerful tools
for configuration?
