An IP address is a unique number given to your computer by your internet service provider (ISP). It identifies your computer when it accesses the internet.
Dynamic IP addresses change - your computer will be allocated different ones at different times. Static IP addresses stay the same and can’t be moved between ISPs.
Note : Static IP and Dynamic IP now both come with an IPv4 address and IPv6 prefix.
A dynamic IP address is suitable if you have:
- several computers on an internal network with internet access on all of them - dynamic IP addresses allow several devices to share limited address space
- a single computer that connects to your head office on a one-way Virtual Private Network
A static IP address is suitable if you:
- run your own website
- run your own email server
- access a virtual private network from multiple PCs via a single broadband service
- run an FTP server
- use off-site server duplication
- use certain security applications, like centralised cameras and polling software
Static IP addresses have a number of advantages. They can give you:
- less downtime - there is a risk of downtime when new dynamic IP addresses are allocated
- remote access - you can access your own PC from anywhere in the world with static IP
