An IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol, which essentially establishes the internet, for communication. Your computer has an IP address, and your smartphone has one too. Websites, which are really just collections of resources hosted on some server, have IP addresses as well.
The problem is that there are not enough IP addresses for every single device connected to the internet, and there won’t be until the mass adoption of IPv6, the most recent version of the Internet Protocol. Until then, you will have to deal with IP addresses such as 192.168.100.1, which is a private IP address commonly used for devices in local area networks (LANs).
Private IP addresses are incredibly useful because they don’t have to be unique. In other words, there can be millions of 192.168.100.1 routers, which is how private IP addresses help delay IPv4 address exhaustion. Apart from the fact that private IP addresses don’t have to be unique, another thing that separates them from public IP addresses is the fact that IP packets addressed from them cannot be routed through the public internet.If you have a 192.168.100.1 router, the router has to remap the private address space into the public address space using a method called network address translation (NAT) before IP packets can be routed through the public internet. As a user, you don’t have to worry about how NAT works, but you should know how to access your router so you can change its configuration and optimize its performance.
Don’t let the 192.168.100.1 IP address fool you into thinking that logging in to a 192.168.100.1 router is difficult. In reality, it’s just as easy as visiting a website. All you need is a computer with a web browser connected directly to the router with an Ethernet cable, which is a popular type of network cable used for high-speed connections between two devices.
Connect your computer with the router using an Ethernet cable. Open a web browser on the computer that you’ve just connected with the router. In the web browser, type the following address into the navigation bar: http://192.168.100.1.
Hit enter and wait a few seconds. Log in with the router’s admin password and username.
If you don’t know the router’s admin password and username, you can try “admin” for both. If that doesn’t work, take a look at the bottom side of the router, there should be a sticker with the routers name, manufacturing number, and, hopefully, the admin password and username.
Should that fail as well, we recommend you google the name of the router or try a few other common default password and username combinations, which include, admin/0000, user/user, root/12345, and support/support.
There are many reasons to log in to a 192.168.100.1 router. For starters, you may want to change your router’s wireless settings to improve the performance of your Wi-Fi.
Let’s say, you’ve used NetSpot, an easy-to-use Wi-Fi analyzer that delivers professional results and can help you discover why websites take such a long time to load in certain parts of your house and discovered that there are many Wi-Fi networks around you broadcasting on the same frequency band and channel as you.
When you log in to your router , you can switch it to a different channel and thus improve the performance of your Wi-Fi. Just make sure to use NetSpot first to figure out which settings you should use and find the best WiFi channel for your router.
By logging in to your 192.168.100.1 router, you can also take advantage of some of its more advanced features, including malware and spam protection, guest Wi-Fi access, virtual LANs and multiple SSIDs, port forwarding, parental controls, remote management, and Quality of Service (QoS), among others.
All network-connected devices can use the 192.168.100.1 IP address or any other private IP address for that matter. It all depends on your router and how you set it up.
Some routers even let you take control of the private address space and pick a subnet, which is the full range of allowable IP addresses, assign a fixed IP address within the subnet to the router, and decide which IP addresses within the subnet will be given out on an on-demand basis to devices that connect to the router, among other things.
While there can be only one 192.168.100.1 IP address in a single network, there can be multiple networks with the 192.168.100.1 IP address. This is typically not something regular home users need to keep in mind, but it’s something network administrators deal with on a regular basis.
Instead of remembering that one 192.168.100.1 IP address refers to a server and another 192.168.100.1 IP address refers to a printer, they often switch to a different subnet to avoid confusion.
The 192.168.100.1 IP address belongs to the private address space, and it’s used by local network devices to identify themselves. Despite its strange appearance, there’s actually nothing strange about the 192.168.100.1 IP address at all, and you can easily access it from any modern web browser.
Just keep in mind that this private IP address can be assigned to all sorts of network-connected devices, including smartphones, laptops, smart TV, smart refrigerators, and even smart lightbulbs.
