Already working:

  • Debian box
  • DHCP with send host-name me.company.com in dhclient.conf
  • DNS updates automatically with an entry for me.company.com

What I want to add:

  • Send a second host-name, so both are automatically registered with DNS

In other words: I want a DHCP client to register with DNS twice using different names, preferably without having to maintain DNS records manually.

Is this even possible with DHCP?

Why not have two IP addresses on a single client interface and send in two DHCP-with-hostname requests, use a reservation if you want to be consistent. Obviously it's a waste of an IP but it should work just fine.

Unfortunately the DHCP protocol does not allow this. The hostname is set via the Host Name Option - see RFC 2132 Section 3.14:

3.14. Host Name Option

This option specifies the name of the client. The name may or may not be qualified with the local domain name (see section 3.17 for the preferred way to retrieve the domain name).

Sadly you can only have one entry per request, so Chopper3's solution is probably the only way.

Why not just create a CNAME pointing to me.company.com? I don't think this is possible with dhclient.

    Because I don't own the DNS servers. :-)

    Then you are out - that is not what DHCP is supposed to do, so there is no way to do it.
