01 / Nameserver delegation
The Domain Name System connects domain names to online services. A delegation points to the authoritative nameservers responsible for a domain’s records. Your registrar or registration provider is usually the first point of contact for changes to a delegation.
Before updating nameservers, confirm that the new provider serves the correct zone. Where in-bailiwick nameservers require glue records, coordinate those records with your registration provider.
02 / Operational responsibilities
Domain holders
Keep registration contact details current, protect account access, and renew registrations on time. Check website and email records after any DNS change.
Registrars and DNS providers
Registrars manage registration transactions and submitted delegation data. DNS providers maintain the authoritative zone and associated records. These can be different organizations, so identify the responsible party before escalating an issue.
03 / DNSSEC and change management
DNSSEC enables validation of signed DNS responses where supported and correctly configured. Confirm support with your registrar and DNS provider. Coordinate signing keys and DS records when changing providers; stale records can cause validation failures.
Cached DNS responses may persist until their time-to-live expires. There is no universal propagation deadline. Plan changes, preserve a rollback path, and test resolution from more than one network.
04 / Reporting a DNS issue
Record the domain, affected query type, resolver used, timestamps with time zone, and the response or error. Share this information with your registrar or DNS provider. Do not include passwords or private signing keys.
