I have a dynamic IP address and I don't want to change it every time I connect to the Internet. I want to get a static IP address; what can I do?
If you're talking about your WAN IP, you need to contact your ISP. Otherwise, you could use a dynamic DNS service like No-IP, if the problem is it being consistent.
If you're just talking about your LAN IP, some routers allow you to lease based on MAC address, or you could just go to Network Settings, right click your adapter, Properties, IPv4, Properties and change it to an IP address within your LAN range.
