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