##Creating a Subdomain That Uses Amazon Route 53 as the DNS Service without Migrating the Parent Domain

---

You can create a subdomain that uses Amazon Route 53 as the DNS service without migrating the parent domain from another DNS service.

example :

Your main domain is example.com but you want to create a subdomain NameServer.

Stat of your domain.

dig ns example.com

;; QUESTION SECTION:
;example.com.			IN	NS
 
;; ANSWER SECTION:
example.com.		3600	IN	NS	ns3.somensserver.com.

Create Subdomain

You want to keep those records, now lets create the subdomain.

On your route 53 create the subdomain :

Create Hosted zone

Fill up the box Domain Name: with your subdomain : k8s.example.com

Route 53 should generate your NS server like :

;; ANSWER SECTION:
ns-613.awsdns-13.net.
ns-75.awsdns-04.com.
ns-1022.awsdns-35.co.uk.
ns-1149.awsdns-27.org.

With your registrar add those NS server to your subdomain.

The result should be.

dig ns k8s.example.com

;; ANSWER SECTION:
k8s.example.com.		172800	IN	NS	ns-613.awsdns-13.net.
k8s.example.com.		172800	IN	NS	ns-75.awsdns-04.org.
k8s.example.com.		172800	IN	NS	ns-1022.awsdns-35.com.
k8s.example.com.		172800	IN	NS	ns-1149.awsdns-27.co.uk.

Wait until the NS replication is ok
