We recently had some issues with DNS on the sipx.* domains and decided we needed a secondary DNS server to keep DNS running should the primary go down. After a little research we signed up with Twisted as a secondary and so far all is looking good. They offer free secondary DNS hosting for up to 10 domains, signup was painless and easy – with clear instructions on what records needed to be added and where.
After getting DNS back up and running and setting up the secondary – we used the superb DNS checker from DNS Stuff (http://www.dnsstuff.com) to verify all was as it should be. Thankfully we did – the report picked up a number of things we’d missed – but the detailed report listed exactly what the problems were and guidance on how to fix them.
Part of the fix involved setting up some glue records for the name-servers – and digging through the GoDaddy management interface. An hour later we managed to find where we could setup the glue records.
If you’re a GoDaddy user and need to do the same:
- Login to your GoDaddy account
- Select Domains
- Select a Domain to manage
- On the summary screen in the bottom left hand corner you’ll see a box: Host Summary
- Once you’re in the host summary page – you can add your own glue records by providing a DNS name and it’s IP address (It’s here you would specify name servers that you manage for the zone)
It’s important to add DNS glue records for domains you manage – it speeds up DNS queries and short-circuits the problem of name servers that are inside the domain they manage; ie: ns1.sipx.ws is a name server for the sipx.ws domain – without being able to plugin an IP address for the name server – DNS doesn’t know how to talk to the domain).
