You're conflating two different things, Gene. DHCP assigns a dynamic IP address. That's the main job. And it will provide a default router along with that. The original poster wants that. It also has lots of optional bits of data that it can provide, but doesn't have to. Among those: - DNS server addresses - default domain names - NTP servers - TFTP servers - NFS servers The original poster does not want their machine to pay attention to any of that, even if it is supplied. The full list, I think, is a little overwhelming: https://www.iana.org/assignments/bootp-dhcp-parameters/bootp-dhcp-parameters.xhtml -dsr-
