A static IP address is a fixed IP address that is assigned to a device and does not change over time. Unlike dynamic IP addresses, which can change each time a device connects to the internet, static IP addresses remain constant. This can be beneficial for certain applications, such as hosting a website or running a server, where a consistent address is necessary for reliable access. Static IP addresses are often used in business environments and for services that require stable and predictable network communication. It is possible to have IPV4 static IP address or IPV6 static IP address.
| IP Version | Total Addresses | Addresses in Use |
|---|---|---|
| IPv4 | 4,294,967,296 | ~3,700,000,000 |
| IPv6 | 340,282,366,920,938,463,463,374,607,431,768,211,456 | ~50,000,000,000,000,000 |
How to Buy a Static IP Address
To buy a static IP address, you typically need to contact your Internet Service Provider (ISP). Most ISPs offer static IP addresses as part of their business or premium plans. The process usually involves subscribing to a specific plan that includes a static IP address or paying an additional fee to add a static IP address to your existing plan.
The organization responsible for keeping track of who owns a static IP address is the Internet Assigned Numbers Authority (IANA). IANA allocates IP address blocks to five Regional Internet Registries (RIRs), which then distribute IP addresses to ISPs and other organizations within their respective regions. The RIRs are:
- ARIN (American Registry for Internet Numbers) - North America
- RIPE NCC (Réseaux IP Européens Network Coordination Centre) - Europe, the Middle East, and parts of Central Asia
- APNIC (Asia-Pacific Network Information Centre) - Asia and the Pacific region
- LACNIC (Latin America and Caribbean Network Information Centre) - Latin America and the Caribbean
- AFRINIC (African Network Information Centre) - Africa
These RIRs maintain databases of IP address allocations and assignments, ensuring that each IP address is unique and properly registered to the organization or individual that owns it.
Why You Don't Need to Buy a Static IP Address for Small Uses
For most small-scale applications, such as personal websites, remote access, or small business services, purchasing a static IP address is often unnecessary. Instead, you can use an internet-based DNS (Domain Name System) service. DNS services allow you to map a domain name to a dynamic IP address, providing a consistent way to access your resources without needing a static IP. This approach is cost-effective and flexible, as it can handle changes in your IP address automatically.

- DynDNS - A dynamic DNS service that allows you to map a domain name to a dynamic IP address, ideal for remote access and small-scale hosting.
What is port forwarding and how to use it with online DNS
Port forwarding is a networking technique that allows you to redirect incoming network traffic from one port to another. This can be useful for hosting services on your network, such as a web server or game server, and making them accessible from the internet. When combined with an online DNS service, port forwarding enables you to map a domain name to a specific port on your network, providing external access to your services.
Conclusion
In conclusion, while static IP addresses offer certain advantages for specific applications, they are not always necessary for most users. Dynamic IP addresses, combined with DNS services and port forwarding, provide a flexible and cost-effective solution for many small-scale needs. By understanding the differences and evaluating your requirements, you can make an informed decision on whether a static IP address is right for you.
