May still allow an attacker to spoof the dns name - or are you using

Yes attacker can spoof the DNS but match pattern with not allow the
request to go through as it will check the referer with our own DNS.

I guess referer contains the DNS from which the request is coming not
the DNS on which application is deployed.

Please suggest if i am wrong.


Referrer is user provided data. It can be easily spoofed. You should not use the referrer for any sort of security.
