DNS Servers

Hi!

We have som partners outside our domain controller so I have created a policy so that they can access one of our websites. But they need to write the IP-address of the websites server in the web browser to access the site. The site need to have a .com/*** for the access. For example service.example.com/it-service

If I, in DNS Servers, create a new entry and type the address service.example.com/it-service and then the IP-address below it says Input value is invalid. But if I only type in service.example.com and then the IP-address below it works. But on the computer I can only access service.example.com but not service.example.com/it-service 

Is there some other way to do this?

Thanks.
