In LightSail Domain & DNS, cannot edit nameserver: Want to continue to use external registrar

Hi,

The screenshot in your post is the DNS zone for a domain which provides NameServers who would act as information providers for queries on your domain-name. Hence these are the server names provided by AWS and can not be edited. But you shouldn't need to ever edit these - let me explain further below :)

If you want to continue to have your domain registered with hover.com and not transfer it to AWS Route53 Domains - that works absolutely fine with using Lightsail resources.

The next choice to make, is where would you like to have your DNS management - does hover.com also provide DNS records management for you and would you like to use that OR do you want to use Lightsail's free DNS management.

If you want to use Lightsail's DNS zone for DNS management, then you would update the NameServers at your registrar side (i.e. at hover.com) with the NameServers listed above in your Lightsail DNS zone. After that you would add any DNS records like an A record for an instance's Static IP or MX records for mail setup, etc to this Lightsail DNS zone and they would take effect once your registrar updates the NameServers ( which sometimes takes time depending on the TLD and registrar ). At this point you would have your domain name registered with hover.com but your DNS managed in Lightsail.

If instead, hover.com provides DNS management as well and you want to continue using that, then you don't need the Lightsail DNS zone at all. You would just add the A records, MX records, etc pointing to Lightsail instance IPs or endpoint names/etc to the DNS management in hover.com

Hope this helps.
