In the portal I added dns zone records for mydomain.com
- A record for the web app ip address and
- TXT record for the web app name with value mysite.azurewebsites.net
I set the name servers to
ns1-04.azure-dns.com
ns2-04.azure-dns.net
ns3-04.azure-dns.org
ns4-04.azure-dns.info
as mentioned in the Azure portal DNS Zones blade
However when I try to add the custom domain to my app service, and I try to validate it Selecting A record for the hostname record type
I get an error on Domain ownership
To verify domain ownership create TXT and A records with your DNS provider using the configuration below
[Update]
I decided to try buying a domain from the Buy Domain option inside the custom domain blade.
The app service worked with this newly bought domain within minutes.
I noticed that this created a www CName record not a TXT record for mysite.azurewebsites.net
Also the name servers mentioned in the Azure DNS Zone were of the format
ns1-07.azure-dns.com
