So it seems it was the chassis ID of the neighbour but i am not sure
why it never updated it to the hostname.

Anyway for now I did a
-------
BEGIN;
UPDATE public.device_port SET remote_id='SW-IDF3.meeting.ietf.org' WHERE ip='130.129.1.30' AND remote_id='00:1e:f7:e8:35:00';
SELECT ip,remote_ip,remote_id FROM public.device_port WHERE remote_id is NOT NULL and ip='130.129.1.30';
COMMIT;
-------

to not accidentally kick the NOC off the DHCP and RA again tonight.
Still interested in a proper fix w/o deleting and rediscovering the device from netdisco.
