Questions: Should we automatically make the suggested changes in the RIPE database?

No.

Or should we send mail to the technical contacts asking them to change things?

Yes, however it could be a good idea to CC to the local-ir contacts. At least for ".AT" I'd like to have this information.

DB remove 129.177.0.0: aun.uninet.no

note: obiously a spelling error in the database :-))
