DNS Adress


I’m new user with CloudFlare. For one customer, i have a problem with nameservers udapte.
The registrar is YULPA. For udapte nameservers, they ask me Ip address.

Thank you for your answer.

Best regards,

Hi @f.bisschop,

You can use a command like nslookup on Windows or dig on Linux/Mac to find the IP, or use an online tool like dnschecker.org and enter the nameservers.


Thanks ! :slight_smile:
