#Modem vs router ip how to#
How to find a modem’s IP addressĪs I mentioned at the beginning of this article, there are two different situations when it comes to your modem and its IP address. This is very important, because there are a few easy changes you can make to your router to make your internet more secure ( we’ll talk more about this later). In accessing your modem, you can review and change its settings. Having an IP address allows you to find your modem on your network. At this point, it’s not surprising if someone has 50 or more internet devices on their network at one time.Īll of these devices will have an IP address.įor the same reason as all your other internet devices. Smart devices (outlets, refrigerators, washing machines, etc.).To make this simple, all of the Wifi devices in your home will have an IP address. If your devices didn’t have an IP address, no one would be able to find or access them. Just like all the houses on a given street have a different address. Why does a modem have an IP address?Ī little bit of background information will help here.Īn IP address basically just defines the location of a device so other devices on your network can find it. Read on to find out all you need to know about your modem’s IP address. The bottom line is, it’s definitely worth your time to find out what your modem’s IP address is. Accessing your modem’s settings will allow you to easily enhance the security of your home network. Your modem’s IP address is important to know, because you need it to access your modem’s settings. If your modem and router are combined into one device, your modem will share an IP address with your router. If your modem is a standalone device that’s separate from your router, it’ll have its own IP address. It may just not have it’s own unique one. One way or another, your modem will have an IP address tied it. So let’s take a closer look at a few questions surrounding modems.ĭoes a modem have an IP address? And why do we care if it does or not? In fact, many home internet users don’t understand what a modem does. Modems are probably the most overlooked device when it comes to your home network. However, each connected device will have a different internal Internet Protocol address as assigned by the modem, router, or DHCP Server.Do you know which devices in your home have IP addresses? Have you wondered why knowing the IP addresses of your devices is important?Ī common subject of these questions is your modem. Therefore, all devices connected to your residential modem or router on your LAN will share the same external, public, WAN IP address. Your residential modem or router acts as a DHCP server and assigns internal IPs to each device connecting to your Local Area Network via wired or wireless connections. It protects the devices within your LAN from exposure to the public. Therefore, in residential settings, the modem or router acts as a firewall. External IPs assigned directly to a computer's NIC (Network Interface Card) have protective measures in place when using this method of connection.
Hence, the use of the word "private" when referring to internal IPs.Įxternal IP addresses are often assigned to a modem or router instead of assigned directly to a computer in residential settings. WANs connect LANs and LANs are private in most cases. CISCO says the first WAN was used by the Air Force in the 1950s. They, then, can all communicate to each other without connectivity to the Internet. You can connect many local devices together within a LAN. A LAN (Local Area Network) refers to your internal network. For example, the Internet considered a WAN. It typically covers a large area therefore, "wide" accurately describes it. In simple terms, your external or public IP address is part of a WAN (Wide Area Network). To clarify, the most common of the three blocks is the 192.168.*.* group. These IPv4 internal blocks are reserved via Internet Assigned Numbers Authority (IANA), and not assigned as public or external IPs. The Internet Protocol address shown on the What Is My IP home page is the public IP address, also referred to as the external IP address from your connection. It can be confusing as to why show a different IP address than IPCONFIG - IFCONFIG? With that said, the following article can hopefully explain the differences!! Internet Protocol (IP) Address
