What Is an IP Address? A Business Guide to IP Addresses
We've got some great deals going on right now exclusively for our online customers... chat now to hear more! Author: Poornima Apte,Date published: September 25, 2025,If you have ever asked "What is an IP address? or What is an IP address used for? the short answer is that an IP address is like a phone number for your internet-connected devices. It is a unique identifier. Any computer needs both an internal and external IP address to connect to another computer over a network using the internet's global language, the Internet Protocol, or IP. There are about four billion unique IP addresses. The , the group of engineers who invent and maintain the technology of the internet, specifies the format of these IP addresses. The IP version 4 format was invented in the 1980s and is still used. It looks like this: 192.168.107.13. The IETF created a newer format with much more room for addresses (more than the stars in the observable universe), so the internet can continue to grow in the future. With that established, let's explore what you'll need to know about IP addresses for your business. Your small- to medium-sized business (SMB) might have a network of its own, where all your computers and various devices are connected with each other. When you send a document to the printer, for instance, your PC uses the printer's IP address to send the data. This business network is private to you; no one else can connect to your printer. Accordingly, the IP address of the printer and of your PC are private addresses, and your network is known as a private IP network.,But you might also have a public service—for example, a catalog on the web where customers can view or order your merchandise or fill out a form. This service or web page must be running on a computer with a public or external IP address so that anyone on the internet can connect to and use the service. This public computer could be maintained for you by a commercial web hosting provider who assigns a public IP address to that computer, or your IT could maintain the computer on your own premises. In this latter case, your internet service provider (ISP) will assign you a public or external IP address to use. Now that you know the answer to the what is an IP address and what is an IP address used for questions, and now that you understand the difference between an internal and external IP address, how do they work as part of your ? When an employee in your business uses an online software as a service, for example, the machine in your network needs to talk to the machine at the other end. Since humans find it difficult to connect using IP numbers, they use a service called Domain Name System (DNS), which takes names like Google.com or Verizon.com and translates them to the corresponding public IP address so that your machine knows where to go. Businesses can choose whether they want addresses to be static or dynamic. Static addresses are constant, just like your business phone number, while the dynamic equivalent changes frequently. While there is an argument to be made for IP addresses to be dynamic to make security more robust, a confers many advantages, including:,In addition, static IP addresses increase reliability and are easier to manage. As the number of devices on business networks increases, SMBs have to manage ease of access with security. Answering the question What is an IP address? and understanding the difference between an internal and external IP address are the first steps in getting there.

Learn moreStatic IP Vs. Dynamic IP Addresses: Understanding the Differences
Author: Gary Hilson,Date published: September 29 , 2025,With the significance of network connectivity in today's connected world, it's essential to understand the difference between a static IP vs. dynamic IP address, their essential contribution to organizing the internet and how best to use them. Deciding between a static IP vs. dynamic IP address can help an organization better support remote users, so they can access the devices they need, no matter where they are, as well as facilitate access to any data, digital information, or services they need to be productive. Every device connected to the internet, or a private network using TCP/IP, has an assigned internet protocol (IP) address, acting as a unique identifier for that device. The most popular network protocol in the world, TCP/IP (Transmission Control Protocol/Internet Protocol), is the standard internet communications protocol that allows devices to communicate over long distances. TCP is the component that breaks down and reassembles the packets of data, while IP is responsible for making sure the packets are sent to the right destination. We will explore IP in this article. The IP address is a unique identifier for devices connected to a network, similar to a postal address. The first type of IP address was IPv4, which has been used since the. The was created to accommodate the growth of internet-connected devices by offering more IP addresses, but to this day, IPv6 is still not enabled by all content and transit providers or products. Older computers and Wi-Fi routers, for example, may not be IPv6-capable. IP addresses are managed and governed centrally through the Internet Assigned Numbers Authority, and although the was announced in 2011, IPv4 are still widely used thanks to technologies like Classless Inter-Domain Routing (CIDR) and Dynamic Host Configuration Protocol (DHCP). CIDR is an addressing scheme that improves the allocation of IP addresses, while DHCP is a network management protocol used on IP networks for automatically assigning IP addresses. What is the difference between a dynamic and static IP address? A static IP address is a permanent number assigned to a computer or device and does not change over time. However, a device that is connected to a dynamic IP address gets automatically assigned a temporary number that can change every time it reconnects with a network. A key aspect of understanding the difference between static IP vs. dynamic IP addresses, is that they are not the only kinds of IP addresses. So exactly what is a static IP address and what are the other kinds of IP addresses? When a static IP address is assigned to a device, it doesn't change until the associated services are disconnected or a request to release the IP address lease is submitted. Learn more in. Static assignments, even through a fixed dynamic address, can help support identity-based protections to authenticate the identity of the user or device. This can allow you to adopt practices such as whitelisting or allowlisting and/or ensure users have the necessary authorization and permissions to access certain applications, data, or services. However, a static IP isn't necessary because it's possible to use dynamic Domain Name System (DNS), where permissions and access are tied behind the scenes. The address might change, but the access is provided through the DNS name. This can be particularly useful for remote workers because static IPs can be used to verify permitted users to access a company network. Furthermore, the addition of private IP networking layers on security as each device will have their company's private IP address, ahead of with the likes of multifactor authentication and single sign-on (SSO), not directly routed over the public internet. Determining between dynamic vs. static IP addresses and when to use each one allows organizations to improve speed, reduce connection delays, address discrepancies and eliminate recognition errors from applications accessing data. Using a static IP vs. dynamic IP address means applications, users and systems accessing the data do not need to track IP address changes. As an example, if your organization is running an e-commerce website and handling payments, a static IP address combined with an SSL certificate is essential for securing customer data. Your organization may also need one if you're running certain third-party applications or scripts on your site. Global CEOs and other business leaders continue to recognize the. This is why it is important to build an understanding of IP addressing and other potential solutions. It's just as important to work with a trusted provider that can guide you and your business.
