Notice that windows lists it under the title Default Gateway. The easiest way to determine your routers external IP address is to visit a website that reports it back to you. We do that for you. Below is your real external IP address as of right now. Network Utilities. Intro Download Buy News Support. Your router's internal IP address is what you use to talk to your router. There are two basic forms of IP address: static and dynamic.
This understandably has its pros and cons. A static IP address can be relied upon to stay the same regardless of other infrastructure developments, meaning IT admins will never encounter a surprise when scanning for IP addresses. However, depending on the size of the network, the manual allocation of all host IP addresses can require a massive amount of time, tracking, and structuring. Especially given that static addresses can become incompatible with a system in various ways, choosing to exclusively use static addresses is largely inefficient and inflexible.
Nevertheless, there are several good reasons to opt for the static IP address system.
How To Find Your Local IP Address In Windows 7 or Vista
The process of assigning a static IP address is lengthy and complicated, so it typically requires a professional. This constraint makes static IP addresses more suitable to a business environment, though they can add benefits to home networks as well. Static IP addresses are helpful when:. Dynamic IP addresses, in contrast, are assigned by the DHCP server, eliminating the need for an admin to spend hours allocating addresses. This automates many of the more irksome details of configuring an IP address system: without administrative oversight, the DHCP server can assign a unique IP address, a subnet mask, a gateway address, and other requisite reference information like the address of the DNS server to all devices.
The advantages of the DHCP system are obvious: it reduces administrative overhead and scales with the environment.
It has its disadvantages, as well, notably regarding the temporary nature of the dynamic IP address. Although the network client can attempt to renew the same address repeatedly, its address is not guaranteed. Particularly when it comes to remote work, attempts to gain access to a distant device or network can fail without knowledge of its current IP address. These potential hiccups have solutions—altering the DHCP scope to exclude static addresses in use; changing DNS scavenging settings to ensure the server purges old records and updates its data—but they require foresight and additional work.
Still, barring slight complications, a dynamic IP address system is the most reasonable solution for large-scale networks. While many enterprises may use a static IP address with their router for remote networking or internet security purposes, DHCP is an efficient, useful system for node address designation overall. While free tools are adept at handling smaller tasks—like simply discovering active IP addresses and correlating them to MAC addresses—a diverse toolkit like those offered by SolarWinds IP Address Manager provides a comprehensive solution.
By performing data analysis, streamlining high volumes of data into insightful graphs, offering useful network visualization, and pushing security and IP address conflict alerts, SolarWinds software can help ensure networks remain in safe, peak-performance shape.
How To Port Forward
Ultimately, through keeping tabs on the many rote and time-intensive tasks required by IP address systems, these robust tools free up administrators to apply themselves elsewhere. Open the command prompt. If the subnet mask is This list is incredibly informative, containing the IP addresses, MAC addresses, and allocation type whether static or dynamic for all live hosts. This will enable you to further narrow down what devices could be experiencing or causing problems.

IP Scanner Free Created by developer 10base-t Interactive and optimized for Mac, this app is admittedly limited; the free version only supports 6 devices. Back to Top The Importance of IP Addresses in Networking Now that you have the best tool in place to scan, monitor, and manage IP addresses on your network, having a baseline understanding of how IP addresses work—including the differences between the addressing systems of IPv4 and IPv6—can also help protect the performance and integrity of networks.
What Is an IP? It allows other devices to find and communicate with the device in question. IPv6 Currently, there are two coexisting standards also called versions for formulating IP addresses: In IPv4 Internet Protocol version 4 , an IP address is made up of decimal digits and contains 32 bits or 4 bytes.
Public vs. Private IP Addresses
At present, the global number of internet-connected devices already far exceeds that threshold, at To compensate, many networks use both private and public IP addresses, so several devices within a local network may share a public IP address but have separate private IP addresses. While this system has worked historically, it poses a couple of problems. First, it introduces an additional step in networking and increases administrative overhead. When two devices share a single IP address, they may not be able to connect to the internet or the local network at all.
IPv6 was developed to circumvent these complications.
Four times larger than an IPv4 address, an IPv6 address contains bits in total, written in hexadecimal, and punctuated by colons rather than periods. Back to Top IPv4 Classful Addressing Basics The number of nodes a network will need to support determines the exact structure of the IPv4 address, which is further classified into different address classes. Class A is typically used in large organizations as it can generate millions of unique node variations.

Class A has an IP address range of 0. Class B can produce tens of thousands of node address variants and is primarily used in medium-sized networks. Class B has an IP range of Since Class C IPv4 address allocates one byte to the host identifier, this tier of IPv4 network can only support a maximum of hosts. Class C has an IP range of Back to Top Classful vs. Classless Addressing Because of fears that the classful IPv4 addressing system was too quickly using up available address variations, the Internet Engineering Task Force developed the Classless Inter-Domain Routing CIDR system to allow for network prefixes sized between the 8-bit intervals instituted by classful networking.
Static IP addresses are helpful when: You want to ensure a shared resource like a printer or server is always accessible to everyone on the network, no matter their device, by giving it an unchanging address You want to use devices incompatible with DHCP You want to avoid IP address duplications, which a faulty DHCP server can generate You want slightly improved network security and geolocation precision compared to a dynamic IP address system Dynamic IP addresses, in contrast, are assigned by the DHCP server, eliminating the need for an admin to spend hours allocating addresses.
