Weird issue with Anyconnect and DNS

lanab

I have a really weird problem with Anyconnect v4.10.00093 and clients trying to connect.

 

The problem is that i can't connect to the ASA based on the IP address, however if i edit the host file in the Windows 10 client and add like 201.1.14.1 test.test.com and use the DNS test.test.com instead it connects fine.

 

Is there a problem with Windows or some odd policy setting for Anyconnect that needs to be changed.

 

If i trace the packets in Wireshark i can see no attempts to connect to the ASA when i am just using the IP but if i use the DNS name it connects fine.

I can also add that the IP address does not have a registered DNS record, i just added that to the host file for troubleshooting.
