It might be helpful to explain why it "reduces traffice over your internet connection." This is why I run a local dns server at my office, and my laptop. A DNS server running in this fashion is termed a caching dns server. Without such, each time your computer connects to a domain name (ie web browsing) it must make a dns query. This means traversing possibly a lan, and then an internet connection to go to an isp's dns server, then returning before the client can actually connect to the web server. The caching dns server retains this entry in memory, whereas the client usually does not. This means the first lookup goes over the internet connection, all subsequent lookups are made either on the local machine or over a lan depending on the setup. Next, in my experience the bandwidth of a line is less important than the response time. So having a caching dns server means a much faster response. True there is less traffic over the line, but what usually matters is that the client is much snappier. Whomever does not have a caching dns server it is worth your time to set one up, regardless of the amount of bandwidth you have. The only way it is not is if the response time to your dns server is <10ms. How to tell the response time?
