[BusyBox] udhcp: FQDN within DHCP requests

[Allan (reply to lists only)]

Stephan;

It sounds like you want a Dynamic DNS Update:

1) busybox DHCP asks for an IP
2) DHCP server gives it a hostname, IP, netmask, defaultroute, etc
3) DHCP updates DNS server's dynamic zone, saying:
   "client-12-31 is now 192.168.1.33"
4) DNS server stores and offers to clients the new A and PTR record:
   "client-12-31.dynamic.abccheese.com IN A 192.168.1.33"

This can be done in an RFC-compliant manner.

If this is not what you want, perhaps you need to tell us what "It would
be Windows-like" means.  What functionality, what action, does the
client now want to do that your system cannot do without DHCP updating
DNS server?
