Zyro's nameservers are:
If you're asked to specify IPs for the nameservers, use the following:
For dns1.zyro.com: 184.108.40.206 (IPv4) or 2400:cb00:2049:1::a29f:1a5e (IPv6)
For dns2.zyro.com: 220.127.116.11 (IPv4) or 2400:cb00:2049:1::a29f:1b95 (IPv6)
Insert the IP addresses only if required by your domain host. In most cases, the nameservers (dns1.zyro.com and dns1.zyro.com) are enough.
Note: Remember that DNS changes can take up to 24 hours to fully propagate worldwide.
