Question: I have requested an SSL certificate from AWS and I opted for DNS validation. Now they are asking me to add a CNAME record to validate. They have provided me the following to be used:

```
Name: xxx.example.com.  [Host field on GoDaddy]
Value: xxx.acm-validations.aws. [Points to field on GoDaddy]
Type: CNAME

```

Now whenever I provide this using GoDaddy DNS interface, it throws an error saying for 'Points to' field:

> 
> Enter either @ or a valid host name such as: `subdomain.example.tld`
> 
> 
> 

Did anyone encounter this issue on GoDaddy DNS entries?

Answer: 
The `Host` field should be filled with xxx (your subdomain) and the `Points To` field with xxx.acm-validations.aws (without dot).
For validating a domain name like `example.com` you just write the first part of `xxx1.example.com.` without the domain name and without suffix dot, like this:

```
TYPE: CNAME
NAME: xxx1
VALUE: xxx2.acm-validation.aws

```

For validating `www.example.com` you just write the first part of `xxx3.www.example.com.` without the domain name and without suffix dot, but including `www.`, like this:

```
TYPE: CNAME
NAME: xxx3.www
VALUE: xxx4.acm-validation.aws

```

You can test above configuration after some minutes with:

`dig TXT +short +noshort xxx1.example.com`

`dig TXT +short +noshort xxx2.www.example.com`
