The list of authoritative DNS servers for your domain will be managed by your domain registrar. If you are unsure who your registrar is, you can find this using the on-line WHOIS query tools available here:
- Internic Whois Search for (.aero, .arpa, .asia, .biz, .cat, .com, .coop, .edu, .info, .int, .jobs, .mobi, .museum, .name, .net, .org, .pro, or .travel)
- WHOIS Lookup at DomainTools.com for most other domains
- Open Directory Whois Listing if neither of the above two can find your domain
Once you have identified your registrar, contact your registrar for instructions on how to change the Name Server delegation. The list of new DNS servers will be provided at the end of the activation process.
