Do you know why people use a static IP address? You have come to the right place. There is a big difference between a Static IP and a Dynamic IP. A dynamic IP can be changed by your ISP or network provider because it is based on a reservation that is determined by your network card’s MAC address. The DHCP reservation is associated with a lease that expires every few hours. But a static IP doesn’t have a reservation at all and stays the same throughout.
In this short guide, you will learn:
What is an IP Address?
An IP address is like a home address for your Internet device. It is a number that identifies a device on the Internet. Just like your house has a permanent address, your device has a unique Internet address that identifies you to websites and services, providing details like your ISP and the country you are located in. You can check your IP address by typing “IP Address” on the Google search, and it appears as a number, for instance, 18.104.22.168.
What is a Static IP Address?
Any IP address that is manually assigned to your device (and which you can also manually set yourself, but as you continue reading this article, you’ll see why that’s dangerous and unwise) is considered a Static IP address. We call it static because the IP address (which is a number) doesn’t change. Your Internet service provider may not assign your device a static IP address based on the agreement you have with them. A static IP address can either be IPv4 or IPv6. A static IP address is best-suited for hosting a server, accessing devices from an external source, or maintaining communication streams.
Using a Static IP Address on Your Internet Network
Your ISP always assigns a public IP address to your Wi-Fi router. Then, the router assigns private IP addresses to all connected devices. The websites and pages you visit online can only check your public IP address.
When you type “What is my IP” on Google, it will show your public IP address that is assigned to your router by the ISP. However, if you are using a VPN for some reason, then the IP address will be assigned by the VPN provider.
The public IP address remains the same on every device. See below.
On a desktop computer:
Private IP addresses are assigned to devices on the home Internet network. For instance, if there are three connected devices, then there will be a different private IP address assigned to each device.
Private IP addresses are also numbers that have specific ranges. If you are using your home Internet network, private IP addresses might fall between 192.168.1.x or 192.168.2.x or so on (but could also be on a 172.16.x.x or 10.x.x.x range). Also, the Internet router has an internal IP address, which might be 192.168.0.1. In this way, the router assigns IP addresses between 192.168.0.2 to 192.168.0.254, but this does depend on your router network settings (and can be changed to one of the other networks as mentioned above ranges).
To make a long story short, you can’t change your public IP address because ISPs assign them to home networks. But if you want to use a static IP address, consider using a VPN connection. A VPN can assign your device a fixed IP address without notifying your ISP and is frankly the safest way to go ahead with a static IP without the risk.
2 Reasons Why You Need a Static Private IP Address
The following are why a static IP address may be beneficial:
1. Create a Server
You might need a static private IP address to forward incoming requests to a specific port that is running a server. If you restart the server (computer), then it may use a new and unique IP address assigned by the router. Ultimately, the incoming requests will have no direction, and the server won’t properly work because outside people connecting to the server only know the old IP.
2. Play MMO Games
Some older generation routers and gaming consoles require you to open ports. Without port forwarding, you can’t play multiplayer games with your friends. However, if you are using a new generation router, then it uses a Plug’n’Play system to open ports on its own.
Why You Must Avoid Configuring a Static IP Address
Best Answer: Firstly, you have to manually set a static IP address and make changes to the router configuration. It must be done on the router level and not on your computer. If you do so on the device that needs the static IP, chances are you might experience IP-related conflicts on the network.
In simpler words, if you set 192.168.0.7 as a static IP address on your smart TV, for example, then the router might assign the same IP address to another device at some point if it’s not set on the router level. Hence, this will create IP-related problems, and one or both networks will fall offline due to the conflict. If you do this from a public IP address, that’d be you setting a much more dangerous precedent. Don’t be surprised if your ISP bans you and blocks you from ever getting back online.
What’s the Solution? Use a Reserved Address…
The easiest way to use the same IP address is to reserve it. If you do this, then you can ensure the devices use the same IP every time you restart them. For private IPs, there are instructions available on how to reserve IP addresses based on the router you are using at home. Whether it is Linksys, UniFi, Netgear, or TP-Link, visit the DHCP Setup and do it on your own. For public IPs, you’re going to have to call your ISP or network provider and pay a premium. Static IPs don’t come for free.
Use a VPN instead
But we have an easier solution that doesn’t require that phone call. You can also choose a VPN, otherwise known as a Virtual Private Network, to route all internet traffic through a static IP address. If your ISP is not offering a static IP address, then consider using a VPN with a dedicated IP add-on, and this will fix your problems.
