[QUOTE="Roland"]\nI prefer the following nomenclature, to avoid the sort of ambiguities\nthrown up in this thread:\n\nStatic IP - you have one address, permanently. Nailed in.\nUsually costs extra.\n\nDynamic IP - you have an IP address which can change as much as once per\nsession, although in practice it might not change so often.\nOverwhelming the most common.\n\nFixed IP - you have an IP address updated by the same mechanisms as a\ndynamic address, but the ISP promises only to change it if\nsomething really drastic happens (like them renumbering\ntheir entire network).\nCan be a sign of a more B2B kind of ISP.[/QUOTE]\n\n\nYour third option is meaningless. Your IP address is either static (by\nagreement with your ISP) or dynamic. I've never known an ISP promise\ninfrequent changes such as you describe.
