Why my domain register requires name servers ip address?

  • 772

I would like to move my domain from main domain registrar name server to amazon Route 53.

The problem is that amazon gives only dns names and my registrar also requires the ip.

Is it safe to use the ip found with the host command? Would my domain work correctly if Amazon decided to change DNS ips?

//added more info:

whois for my domain returns:

beast:~ viroos$ whois domain.name

DOMAIN NAME:           domain.name

new DNSes IPs:

beast:~ viroos$ host ns-475.awsdns-59.com
ns-475.awsdns-59.com has address 205.251.193.219

beast:~ viroos$ host ns-526.awsdns-01.net.
ns-526.awsdns-01.net has address 205.251.194.14

And my question is: Is it safe to fill web form in my current registrar web panel with following data (he requires exact 2 servers). Of coures I added appropriate A, MX and CNAME entries on new server:

NS1 name: ns-475.awsdns-59.com NS1 ip: 205.251.193.219
NS2 name: ns-526.awsdns-01.net NS2 ip: 205.251.194.14

    They have a field for IP addresses in order to utilize glue records - but they shouldn't be required. If they are, your registrar needs to fix their management tools.

    The NS record delegation that's configured for your domain must be DNS names; an IP address is only useful when the servers are within your own domain.

  2. Your current registrar probably also hosts the zone; you can easily verify this by running whois domain.name.

    If you move the domain to another registrar, they will no longer host the zone for you, and you will not be able to use the same nameserver IPs for the new registrar (since they belong to the old one.)

    Just tell the new registrar that you want them to host the zone for you.
