Hi Bill,

Thank you. I'm trying to find out if this feature is already in ISC's short term roadmap. I'll post this information.

* OS: Linux (Fedora 22)

* Subject:man page dhcpd.conf update-static-leases

Bug Detail

The man pages for dhcpd.conf states that for update-static-leases:

This can only work with the interim

DNS update scheme

Does it not also work for the ddns-update-style standard scheme?

It should work for both schemes.  I've tried it and it worked fine in my tests

if it doesn't for you please update this ticket.


Also update-static-leases does not work for either scheme when using



host bigbird { host-identifier option dhcp6.client-id

00:01:00:01:1d:73:5b:05:00:25:22:36:97:f9; fixed-address6



We haven't added support for DDNS with v6 static leases yet.

I'll put it on our list of requests.



Thank you for your bug reports,
