Overview
An Internet Protocol (IP) address is assigned to any machine that is connected to the internet. However, not all IP addresses are created equal. If you’re working with computer networks or servers, you’ll need to know the distinction between dynamic and static IPs. You can select the most suited solution for your needs by learning more about each protocol.
We use internet Protocol (IP) addresses to connect the internet and your network. Static and dynamic IP addresses are the two types of IP addresses. This article compares the advantages and disadvantages of static and dynamic IP addresses so you can decide which one to use. We’ll look at the differences between static and dynamic IP addresses in this article. We’ll also show you how to find your IP address and assign it a fixed number.
What is an IP address?
A TCP/IP network’s IP address is a unique number assigned to each device. IP addresses are unique identifiers for computers and devices that allow them to connect with one another. IP addresses are kept as numbers on the internal network. Humans, on the other hand, prefer names to numbers. The Domain Name System (DNS) is an internet address book that allows you to explore the internet and address devices on your network using words rather than numbers. Those devices might be anything that connects to the internet, including laptops, televisions, smart speakers, and even your refrigerator. Almost every technological device in your house now has an IP address. When you put a URL into your browser, we will be using DNS to find the domain’s IP address.
What is a static IP address?
An IP address that does not change is known as a static IP address. When your device is given a static IP address, it usually stays that way until it is retired or your network architecture changes. Servers and other essential equipment typically utilize static IP addresses. Internet Service Providers (ISPs) assign static IP addresses (ISPs). Depending on the terms of your service agreement, your ISP may or may not assign you a static IP address. A static IP address might be IPv4 or IPv6; the crucial quality is static in this situation. Every piece of networked equipment we own could one day have its own static IPv6 address. We have a long way to go. For the time being, permanent addresses will be normally assigning as static IPv4 addresses.
What is a dynamic IP address?
Dynamic IP address, as the name suggests, can change at any time. Dynamic addresses are assigned by Dynamic Host Configuration Protocol (DHCP) servers on a need-to-know basis. Because there aren’t enough static IP addresses available in IPv4, we need dynamic addresses. Your ISP’s DHCP server may assign a dynamic IP address to your home or office when you connect to the internet. Your network router is likely to assign dynamic IP addresses to your devices within your home or business network, whether they are personal PCs, cellphones, tablets, or whatever else. The Dynamic IP standard is used by and for consumer electronics.
Advantages of a static IP
Using a static IP address has a number of advantages. Among the advantages are:
- Improved DNS support: DNS servers make setting up and managing static IP addresses considerably easier.
- Server hosting: Having a static IP address makes it easier for clients to discover you via DNS if you’re operating a web server, email server, or any other form of server. In practice, this implies that clients with a static IP address will have an easier time accessing your websites and services.
- Convenient remote access: Working remotely using a VPN or other remote access applications is easier with a static IP address.
- More dependable communication: Using Voice over Internet Protocol (VoIP) for teleconferencing or other voice and video communications is more accessible with static IP addresses.
- More dependable geolocation services: With a static IP address, services can match the IP address to the device’s physical location.
Disadvantages of a static IP
A static IP address isn’t always the best option.
- Static IP addresses are more vulnerable to hacking: With a static IP address, hackers can pinpoint your server’s location on the internet. It will be easy for them to assault it as a result of this.
- Higher cost: Static IP address are often more expensive, especially with consumer ISP plans. Static IP addresses are usually included in business ISP plans. However, they are more costly than end-user plans.
- Security risks in the real world: Anyone with the correct network tools may locate you and your computers.
Advantages of dynamic IP
Static IP addresses are more difficult to manage and deploy than dynamic IP addresses.
- Simple, automatic configuration: When a device has a dynamic IP address, the DHCP server assigns it the following available IP address. You are not required to take any action.
- Lower fees: Using a dynamic IP address usually saves you money.
- Unlimited IP address: You can reuse IP addresses with dynamic addresses. Your devices are automatically assigned a new dynamic IP address within a network as needed. So, if you bring home a new computer, you won’t have to manually remove the old one or assign it a number because the network or router will handle it. This reduces confusion when two computers try to use the same IP address.
- Better security: A dynamic IP address makes it more difficult for an attacker to target your networked equipment. You can also improve your security by using a VPN to hide your network address.
- Better physical security: It’s considerably more difficult for snoops to figure out where you are. A VPN can also assist with this.
Disadvantages of a dynamic IP
Dynamic IP addresses aren’t always the best option. They are ineffective for internet-based services like the web or email.
- Unlikely to function effectively for hosted services: Using a dynamic IP address to host a website, email server, or another service can be problematic. Because the address is always changing, DNS does not perform effectively with dynamic IP addresses. There are Dynamic DNS services that solve this problem, but they come at a cost and add complexity. This can be a significant disadvantage.
- Use of a dynamic IP address may limit remote access: If you use a dynamic IP address, your remote access software may have problems connecting.
- More downtime is possible: While it doesn’t happen very often, your ISP may be unable to provide you a dynamic IP address. Your internet connection may be disrupted as a result of this. For a single customer, this is a minor irritation.
- Geolocation accuracy is less precise: Your geolocation services may fail due to a changing IP address. That’s because you can keep a dynamic address that no longer corresponds to your actual location.
Bottom Line
Most internet and web hosting providers assign dynamic IP addresses. However, in other cases, such as when accessing a company VPN with allowed listed addresses, you’ll require a static IP. Businesses that host their own websites and online services usually benefit from static IP addresses. Static IP addresses are also useful for remote workers who use a VPN to connect to the office. Most consumers can get by with dynamic IP addresses. They are less expensive and usually pose a lower security risk.
