The two big advantages are flexibility and expandability. Beyond that, DNS is just A records (mapping domain names to IP addresses). Other resource record types you may find useful are CNAME records, which allow you to create aliases for a domain, PTR records allowing you to translate IP addresses back to domain names, MX or mail exchanger records to handle routing of mail and SRV records, which allow you to create named services. There are a few other resource records having to do with DNS administration and lookup, such as SOA (Start of Authority) and NS (name server).
Actually, 30 is a big number: that's already 435 pairs of addresses. You may want to make part (or all) of your network non-routable, you may want to set up proxies, you may want to make it possible for people to send mail from outsidwe your facility to one or more systems within your facility. You may have occasion to expand, introduce new technologies or just move systems (all of which can force renumbering), you may want to centralize name administration so that you don't have to set up host files on each of your systems separately. You may want to use a protocol like DHCP to dynamically assign IP addresses. You may want to partition your LAN due to network bottlenecks. I suppose I could keep going, but there are a lot of areas in which use of domain names can make your life easier. --- Thurman Pedigo <[EMAIL PROTECTED]> wrote: > Lets say we have 30 devices.
