The DNS protocol is used to resolve FQDN (Fully Qualified Domain Names) to IP addresses around the world. This allows us to successfully find and connect to Internet websites and services no matter where they are. Its usefulness, however, doesn't stop there: local company and private networks also rely on DNS to operate efficiently and correctly.

In many cases, where a local DNS server is not available, we are forced to either use our ISP's DNS servers or some public DNS server, however, this can sometimes prove troublesome. Today, small low-end routers have the ability to integrate DNS functionality, making life easier, but so do Cisco routers - they simply have to be setup and you're done.

This article will show you how to configure your Cisco router to provide DNS services to your network, and make all clients use it as a DNS server. Our easy to follow step-by-step process ensures you'll understand the process and have it running within minutes.
