I have a network in which DNS is automatically updated with a record for hosts when they get an address via DHCP (isc-dhcp-server & Bind configured with DDNS updates). The DHCP server is configured so that a certain host with a complicated hostname gets a friendlier mapping [foo] on the DNS server via 'ddns-hostname' option in dhcpd.conf. I also want this host to have a second record [bar] so it can be resolved via either name. Since Dynamic DNS is in place, it is not possible to modify the zone file manually (normally I could just add multiple CNAME records).
How can I accomplish having multiple DNS records for a host via DDNS? The 'ddns-hostname' option only allows one value, and having a second 'ddns-hostname' entry simply overwrites the first.
