Introduction

In the realm of networking, the choice between a static IP and a dynamic IP is a fundamental consideration that significantly influences how devices communicate over the internet.  A Static IP remains fixed, providing a stable and unchanging address, while a Dynamic IP is assigned dynamically by a server, offering flexibility but with a periodically changing identifier.

Difference Between Static IP and Dynamic IP

This article will cover the following topics: what is an IP Address, what is Static IP, what is Dynamic IP, Difference between Static IP and Dynamic IP.

Let’s start learning about Static IP and Dynamic IP.

What is an IP Address

An IP address is a unique series of numbers uniquely identifying a computer on a network. 

Dots separate these series of numbers. IP addresses are needed so that each computer can communicate with the other in a network.

For instance,

An IP address in dotted decimal form: 128.20.1.32

The Same IP address in binary form: 10000000.00010100.00000001.00100000

There are currently two versions of IP: 

  1. IPv4
  2. IPv6

What is Static IP

A static IP address is also known as a fixed IP address. Static IP addresses are used much less than dynamic IP addresses but are beneficial for several reasons. For example, The

Website requires a static IP address to find and access them without a search. This also allows users to bookmark websites because the bookmark points to the same IP address every time they access it. Static IP addresses are required for VPNs (Virtual Private Networks), a remote connection between two computers or one computer (client) and a server. This allows users to access files and share information remotely. Static IP addresses are also used for online gaming as they enable a server to automatically recognize a player and restore their score, achievements, settings, and in-game placement.

Advantages and Disadvantages of Static IP 

Advantages

  • Speed: Static IP addresses are very less contradictory. So the devices assigned with a static IP address tend to perform faster. 
  • Security: The security offered by a static IP address is always up to a great extent. There is an additional layer of protection that makes sure that most of the security problems are prevented.
  • Stability: All Static IP addresses are highly stable because they are restricted from changes. Whenever there is a reboot, the computers will be able to reconnect quickly to the internet using the same IP address.

Disadvantages

  • Cost: The cost involved in a Static IP address is far greater than that of a Dynamic IP address. It costs more than three times to host a static IP address compared to a Dynamic IP address.
  • Maintenance: Static IP requires more maintenance than Dynamic IP because if a device with Static IP is moved to a different network, the IP address needs to be manually reconfigured. 
  • Availability: The Static IP address can only be assigned to one computer at a single time because each computer needs to be assigned  a unique IP address that cannot be used by the others.

What is Dynamic IP

A dynamic IP address is the exact opposite of a static IP address. While  Static IP addresses are always the same, Dynamic IP addresses change whenever the user connects to the internet or a device is restarted. A modem assigns and keeps track of individual IP addresses within the network and represents all these devices under one master IP address. While the master IP address is highly dynamic and can change whenever the modem is restarted, other devices generally have the same IP address, even when restarted. In this case, dynamic IP addresses come into play because they allow devices to access the internet without requiring each one to have its static IP address.

Advantages and Disadvantages of Dynamic IP

Advantages

  • Simple and automatic configuration: The DHCP server uses the dynamic IP address to automatically assign the next available IP address to the device.
  • Unlimited IP addressing: Dynamic addresses allow you to reuse IP addresses. In the network, a new dynamic IP address will be automatically configured for the device as needed.
  • Better Security: With a Dynamic IP address, it is difficult for potential attackers to target your network equipment.

Disadvantages

  • Restrict remote access: If you use a Dynamic IP address, depending on your remote access software, your program may not be able to connect.
  • Inaccurate geographical location: A Dynamic IP address will make your geographical location service fail because you can keep a dynamic address that no longer reflects your actual location.

Main Differences between Static and Dynamic IP address

The main differences between static and dynamic IP address are:

1. Stability vs. Flexibility:

  • Static IP: Provides a fixed, unchanging address. Ideal for devices requiring a consistent, permanent connection, such as servers or routers.
  • Dynamic IP: Assigned dynamically by a server. Suited for devices with changing network configurations, promoting flexibility in addressing.
     

2. Manual Configuration vs. Automatic Assignment:

  • Static IP: Requires manual configuration, with the user specifying a permanent IP address.
  • Dynamic IP: Automatically assigned by a DHCP server, streamlining the setup process and accommodating dynamic network environments.
     

3. Identification and Accessibility:

  • Static IP: Offers a constant identifier, facilitating easy access for tasks like remote access or hosting services.
  • Dynamic IP: Identifier may change periodically, requiring methods like Dynamic DNS for consistent accessibility.
     

4. Network Security:

  • Static IP: Generally considered more secure, as the address remains constant, reducing the likelihood of unauthorized access.
  • Dynamic IP: Offers a layer of security through address variability, but frequent changes can make tracking more challenging.
     

5. Cost Implications:

  • Static IP: Often comes at a higher cost due to the permanence and dedicated nature of the address.
  • Dynamic IP: More cost-effective, suitable for environments where a fixed address is not essential.
     

6. Suitability for Specific Applications:

  • Static IP: Well-suited for applications like hosting websites, remote access, and online gaming where a consistent address is crucial.
  • Dynamic IP: Ideal for general internet use, where frequent changes in IP addresses are inconsequential.
     

7. Management Complexity:

  • Static IP: Involves manual configuration and may require more hands-on management, especially in large networks.
  • Dynamic IP: Simplifies management by automating address assignments, reducing the administrative burden.

Comparison between Static IP and Dynamic IP

Static IP

Dynamic IP

Static IP addresses are always the same and can’t be modified.

Dynamic IP addresses can be changed at any time.

Static IP addresses are provided by ISP (Internet Service Provider).

Dynamic IP addresses are provided by DHCP (Dynamic Host Configuration Protocol).

It is easy to trace a device using a Static IP address.

It is difficult to trace a device using a Dynamic IP address.

The Stability of a Static IP address is more than a Dynamic IP address.

The Stability of a  Dynamic IP address is less than a Static IP address.

Static IP addresses are less secure.

In dynamic IP addresses, the amount of risk is less as compared to  Static IP addresses.

Static IP addresses are difficult to assign or reassign.

Dynamic IP addresses are easy to assign or reassign.

The Maintenance cost of a Static IP address is more than a Dynamic IP address.

The Maintenance cost of a Dynamic address is less as compared to a Static IP address.

Frequently Asked Questions

Which type of IP address helps host a website? 

Static IP addresses are particularly helpful for events such as hosting a website. With a Dynamic IP address, every time the address changes, the router won’t know which device in the network is the one hosting the site.

Is Static or Dynamic IP faster?

The speed of a network connection is not inherently determined by whether an IP address is static or dynamic. Both static and dynamic IPs can offer similar speeds. Network speed depends more on factors like bandwidth, network infrastructure, and overall system performance.

How is the allocation of IP addresses provided by the ISP different from DHCP?

An ISP is allocated a range of IP addresses. The ISP assigns each address to its networked computers via the DHCP server, which is configured to allocate Static IP addresses to specific computers.

Is static IP Safer Than Dynamic?

Static IPs are often considered more secure than dynamic IPs. A static IP provides a constant, unchanging address, making it less susceptible to certain types of cyber threats. Dynamic IPs, with their changing addresses, can offer a layer of security through variability, but they may be more challenging to track.
