DNS delegation
Nameservers decide which provider publishes the entire DNS zone. Before changing them, make sure the new provider has every website, mail and verification record the domain needs.
Whole-zone changeNot one record only.
Copy records firstWebsite and mail depend on them.
Caches take timeOld routes can remain briefly.
What changes
A nameserver change can affect the website, mail, subdomains, verification records and third-party services together. It does not copy the old zone automatically.
Prepare first
Record the current A, AAAA, CNAME, MX and TXT values. Confirm the new provider is answering correctly before changing delegation. UKC parking uses ns.ukc.uk and ns2.ukc.uk.

After saving
Registry and resolver caches can retain the previous delegation. Avoid making conflicting changes at both providers, and use Domain Diagnostics to check the public route.
