Priority fixes for avinor.no
Ordered by impact and by how common each practice is among peers.
Priority 1 · Recover
Nameservers spread across providers
Observed: All nameservers for avinor.no belong to a single operator.
Why it matters: If every nameserver belongs to one provider, a problem at that provider can stop your domain resolving. RFC 2182 (BCP 16) recommends spreading secondary servers across diverse networks.
What to do: Treat this as an advanced step. Add a secondary DNS provider through zone transfers or a multi-provider setup, then test changes carefully, since both providers must stay in sync.
On Cloudflare: Cloudflare supports zone transfers for primary or secondary DNS setups on eligible plans.
19% of Airlines peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.
