Absolutely - DNS is used for all sorts of purposes.

Some interesting use cases are service discovery[1], replacing the 
traditional model of trust in browsers for HTTPS[2], authenticating 
email with DKIM[3], establishing SSH host key trust[4], aiding in the 
prevention of spam[5].. and many many more. Not all these examples are 
practical today, but they do provide examples of DNS functions which are 
outside the scope of OpenStack Networking.
