Azure DNS for Public IP

Question

I have your VM public ip address

xxx1.northeurope.cloudapp.azure.com

I want to add 1 TXT record in DNS, for this purpose I created the following DNS zone

xxx1.northeurope.cloudapp.azure.com

then added 1 record

test TXT 3600 TEST

however i can't solve it

dig TXT +noadditional +noquestion +nocomments +nocmd +nostats xxx1.northeurope.cloudapp.azure.com. @8.8.4.4 northeurope.cloudapp.azure.com. 60 IN SOA ns1-201.azure-dns.com. msnhst.microsoft.com. 10001 900 300 604800 60

I can only resolve with the zone's name server: ns1-02.azure-dns.com.

dig TXT +noadditional +noquestion +nocomments +nocmd +nostats xxx1.northeurope.cloudapp.azure.com. @ns1-02.azure-dns.com. northeurope.cloudapp.azure.com. 300 IN SOA ns1-02.azure-dns.com. azuredns-hostmaster.microsoft.com. 1 3600 300 2419200 300

I can't solve it from outside

what could be the problem?

I hope to get TEST DNS record

The issue usually occurs if you have not updated the name servers for DNS zone to point to the Azure DNS name servers.

In virtual machine make sure to change public Ip in static like below:

Create a DNS zone with the same name of domain add name server.

Update the name servers for your domain like below:

ns1-02.azure-dns.com
ns2-02.azure-dns.net
ns3-02.azure-dns.org
ns4-02.azure-dns.info

The changes to the name servers may take some time to reach all of the DNS servers on the internet after you make changes. Refer this by GOWTHAM K.

You can use dig +trace TXT test.xxx1.northeurope.cloudapp.azure.com query is being resolved step by step any misconfigurations in the DNS.

In DNS record map @ and type A alias TTL and Ip address and you can add subdomain www as canonical name record, txt record and validate:

Now, when I ran nslookup it properly shows public Ip address and name server successfully like below:
