Static and dynamic IP addresses are two types of Internet Protocol (IP) used by all major websites for email services, file transfers and so on. Static IP addresses remain the same every time you connect to the internet, whereas dynamic IP addresses change every time you connect or send a message over the internet.nBusiness broadband often provides static IP addresses. This is important for businesses that require remote access to their networks, host servers, or run services that rely on consistent IP addresses. nHome broadband generally uses dynamic IP addresses that change periodically.
