Domain & DNS

Practical guides for domain routing and A, AAAA, CNAME, MX, TXT, NS and TTL records, and for checking that your site and email point to the right place.

DNS is the address book that connects your domain to your server. When a site does not open, email stops arriving or an SSL certificate fails to validate, the cause is usually a missing or wrong DNS record. The articles in this section help you connect your domain correctly after buying a hosting or VDS plan, move between servers without downtime and confirm that a change has propagated.

Start with the DNS records guide, which explains every record type with examples; if you want to run your own name server, setting up DNS with BIND walks through it step by step. Check whether your records have propagated with the free DNS lookup tool, which queries four resolvers, and see a domain's registration and expiry details with the whois lookup.

DNS records of domains registered with Fiberserver are managed from the client area; on hosting plans you edit them in cPanel's Zone Editor.
