Other addresses are dynamic, which means the device could potentially have a different IP address each time it connects to the Internet. Sometimes, that address is static - that means the address remains the same and the device will always have that address when connected to the Internet. All computing devices connected to the Internet have an IP address. That's it you should be done! If you can't connect to the internet go back and change your configuration back to what it originally was.An IP address is like an identity on the Internet. That is all that there is to configuring a static IP address on your Mac. Ask them what DNS servers you should be using, and they will most likely give you two ip addresses to type into the DNS Servers box on this page. The easiest way to find out what dns servers to use is to give your ISP a call. We also need to enter the DNS servers that your computer should connect to. Then click the Find Static IP Addresses button. Just enter your computer's default gateway and the ip address your computer is currently using into the form below. I'm going to recomind some Static IP Addresses for you to use here. Every device that connects to your network needs to have it's own IP address. The IP address you choose should end with a number between 1 and 254, and should not be the same as the router's IP address. Only the last number of the IP address should be different. The IP address you choose should be very similar to the router's IP addres. Pick an IP address and enter it into the IP Address box. Then click the Configure button which is close to the bottom of the screen.Ĭlick the Configure IPv4 drop down box and select the Manually option.Īs you can see the Subnet Mask and the Router fields are already filled out. The green dot means the connection is active. It will be the one that has a green dot in front of it. Select the network connection you use to connect to the internet. In the Internet & Network section click the Network icon. If you have a printer, before you begin print out this page!Ĭlick the Apple icon in the upper left hand corner of your screen. The dynamic IP address server is generally refered to as the dhcp server. So when you asign a static IP addresses, it's important to assign an IP address that will not be handed out to other computers by the dynamic IP address server. So the very same IP address may be handed to another computer later, and that will prevent both computers from connecting to the internet. When you set your computer to a static IP address, the router does not know that a computer is using that IP address. The router then hands it an IP address that has not already been handed out to another computer. Every time a computer reboots it asks the router for an IP address. When IP addresses are assigned dynamically, the router is the one that assigns them. The end user can simply plug their computer in, and their network will work. They do this because dynamic ip address networks require no configuration. For more information on IP addresses, subnets, and gateways go hereĭynamic vs Static IPs Most routers assign dynamic IP addresses by default. But if you want to know more about how networks work, you'll find it there. There is a lot of information at the following link. If they do, neither of them will be able to connect to the internet. Every computer has at least one IP address, and two computers should never have the same IP address. IP addresses are four sets of numbers separated by periods that allow computers to identify each other. So the port forwarding configuration will not work. When this happens the ports will no longer be forwarded to your computer's IP address. This will probably work when you initially set it up, but after restarting your computer, it may get a different IP address. When you have port forwarding setup, your router forwards ports to an IP address that you specify.
It is very important to setup a static IP address if you are going to use port forwarding.
