dns server

do I need a dns server? what does it do ? if so is the third party better than free? I have charter communications with up to 30 Mbps speed. I keep hearing about this will it make my speed faster or will I be wasting with it if I buy it. If I do need it how do I go about getting it and setting it up.  Thanks everyone

If your network is online and it's using Charter Communications, you are already using their DNS server.

If you are simply hosting a service and have no requirement for an AD design there is no need for DNS, truth be told as far as performance and redundancy go you are better off to utilize a public name service than to setup your own.

There is absolutely no advantage I can see weighed against the type of infrastructure in place by most of these larger DNS providers.

DNS resolves computer/web names like "www.google.com" to IP addresses, which is optional in your circumstance. It might speed up your web browsing a little, but not at the expense of setup and maintenance. If you want to customize your DNS experience, you can use a public service like OpenDNS. I use to control which web-sites my kids can access from home.

so does that mean I do not need one since charter already is providing dns  server. and speed won't improve even if I added an extra one.

I don't think you need one. Unless you have a server running Microsoft's Active Directory service, then it is required.

Exactly, like I said their redundancy and infrastructural capacity would prove to be more beneficial in the long run than the added overhead of your own.
