I also think it's OK: looking through the CVS log, it seems Frédéric just forgot the case renew/rebind. I'll check with the RFC and add it if there's nothing against it there.

This looks OK to me, but I'm not all the familiar with the DHCP code.  Would anyone else care to comment?

When the DHCP lease times out a renew (or rebind) request doesn't reregister the host name (where one is defined for that netif). This causes a problem on systems which use this to create a dynamic DNS record, such as some routers.

Windows CE had a similar problem described in
 http://support.microsoft.com/kb/821388

This patch reregisters the name.

Tested with Linksys WAG54G router: previously the name in the DHCP status page would vanish overnight when the lease expired, now it does not.
