What is the difference between Static IP and Dynamic IP?


First of all, we have to make sure we know what an IP address is in general. In common English, an IP is the “street address” for a server, computer or device on the internet. IPs are made up of four “octets,” and each octet is a number between 1 and 256. Between each octet is a period. For example, an IP address looks like this: “12” is an octet, “34” is an octet, and so on. IP address is divided into 2 types: a: Static IP. b: Dynamic IP. Let us check the key differences between a static and a dynamic IP.

What is a Static IP Address?

A static IP address is a fixed IP address that is manually assigned to a device on a network. It is called a static IP because it is not changed each time the device is switched on. Static addresses remain the same each time you connect to the network or send a message.

A static IP gives you your very own traffic lane that leads directly to your website. It often makes your site load faster as a result. Since the IP doesn’t change, it is also essential for VPNs, setting up remote access and online gaming.

When Should You Use a Static IP?

Static IP addresses provide greater reliability for applications such as voice over Internet protocol (VOIP). If you run a service that permits incoming audio or video, you may need to use a static IP. For example if you have an on-site IP-PBX, you will need to have at least one static IP address.

A static IP will also be required if you have a machine that functions as a server and requires external access from the users online. This includes running a web server, e-mail server, FTP server, or DNS server. A static IP allows you to enjoy faster upload speeds which boost the efficiency of these services.

If you intend to host a gaming website or you want to use Play Station, X-Box or a VPN to provide secure access to files from your corporate network server, you should also consider buying a public static IP address.


What is a Dynamic IP Address?

A dynamic IP address changes each time you boot your machine or network device. It also changes when you dial into your Internet service provider. Some ISPs change your IP each time you log on to their network while some make the changes periodically.

Most dynamic IP addresses are assigned using the Dynamic Host Configuration Protocol (DHCP). The router on your home network assigns IP addresses to your computers and other network devices as you put them on. Private IP addresses usually have this format: 192.168.0.x. Your router’s IP address will usually be while your computers will be assigned numbers ranging from to

In situations where you need to remotely administer a particular computer on a network, you may need to reserve a particular address for it. To assign static IPs to certain computers and dynamic IPs to others on the same network, you should reserve the IPs for the specific machines on the DHCP server. This will help you to administer the network centrally without the need to assign static IPs manually. It will also prevent the occurrence of IP conflicts.

When Should You Use Dynamic Ips?

Dynamic IPs will be good for anyone who uses their computer or home network for the following:

* Browse the Internet and upload or download files
* Send and receive email through a mail server or via a web based email service like yahoo mail, hotmail or gmail.
* Use online chat services or instant messaging
* To use FTP servers or web servers that only require access from your LAN or corporate network but do not require access from the Internet.



A Static IP address is a dedicated IP address that has been assigned to you. This is an IP address that is used by you every time you log in to network and need an IP address. DHCP or Dynamic is an IP address that will automatically be chosen for you from a pool of IP addresses that are assigned in the DHCP scope available on your network. Think Static as permanent and DHCP as temporary.
