What are nameservers?

Nameservers are the servers in charge of your domain’s DNS. What they do, how they differ from DNS records, and where they’re set.

Nameservers are the servers that hold the authoritative DNS records for a domain. Setting a domain’s nameservers decides who answers questions about it — and therefore where you manage its records.

Where they’re set

At your domain registrar. This is the one DNS setting that isn’t changed at your host, because the registry needs to know where to send lookups before your host is involved.

Traxio’s nameservers

  • ns1.traxio.co.uk
  • ns2.traxio.co.uk
  • ns3.traxio.co.uk

Multiple nameservers provide redundancy: if one can’t be reached, resolvers ask another.

What changes when you switch

Pointing a domain at new nameservers means the records on those nameservers become live, and records held at the old provider stop being used, all at once. That’s why email can stop after a switch if its records weren’t recreated. Email stopped working after changing nameservers

With Traxio nameservers

  • Your website, www, mail and subdomain records are created automatically
  • You edit records in Account Manager then DNS Management
  • SSL certificates issue without further setup

Common confusion

Nameservers aren’t where your website is — they’re who says where your website is. Nameservers vs DNS records: what’s the difference?
