Add your domain to Serv00 as usual
Go to DNS Zones, open your domain's zone and copy the IP of the A record from there
Go to dnsexit.com and edit the "Host Records" with the IP you copied
Go back to your domain's DNS zone on Serv00 and add 4 NS-type records as follows:
Entry: @ Type: NS Target: ns10.dnsexit.com TTL: leave as is
Where Target will be ns10.dnsexit.com, ns11.dnsexit.com, ns12.dnsexit.com and ns14.dnsexit.com - create a different NS record for each.
You can now delete the default serv00 NS records and the A record as well.
Copy the other records to dnsexit.com and delete them too, leaving only the NS records.
All done!
