I was thinking about changing my name servers to point to my own DNS Server as the primary server and a “Friend of a Friends” name server as the secondary.
My VPS is running PowerDNS which is simple enough to add in regular DNS entries, my biggest head ache was the SRV record as I needed to add:
In Windows DNS it was pretty straight forward but in PowerDNS it proved a bit for tricky. I tried several different ways of adding it but it would not let me un till I put the following:
Name of the record: _sipfederationtls._tcp
Type: IN SRV
Content: 1 5061 sipfed.online.lync.com
I hit add and it added the record and seemed to like it. now all I have to do is point my name servers from their current name servers to the two new ones…
…see you on the other side.
My DNS server updates the secondary automatically so all settings should be propagated to the secondary in the event that my server falls over
