Static vs. Dynamic IP Addresses

IP addresses connect the internet to its 5 billion users, facilitating essential communication across every website, computer, router, and device online. With over 4 billion IP addresses in use, 600 million of which are reserved and unavailable for public routing, the strategic allocation and management of these addresses become crucial.

As such, entities involved in reseller hosting, play a pivotal role in ensuring that their clients can effectively manage and utilize IP addresses. This capability is essential given the distribution of IP addresses, with the United States controlling approximately 36.43% and China 10.32%, highlighting the global necessity for skilled IP management.

What Is an IP Address?

An IP or an Internal Protocol address is a unique address that serves as an identifier for each device that connects to local networks or the Internet.

IP addresses allow devices on the same network to communicate and share data. They provide location information and help devices find each other.

Different IP addresses are used for websites, computers, and routers to help identify each one.

The Transmission Control Protocol/Internet Protocol (TCP/IP) sets the rules for how data is exchanged through IP addresses.

The Internet Assigned Numbers Authority (IANA) manages the allocation of IP addresses.

IPv4 and IPv6

IP addresses consist of four number sets ranging from 0 to 255, separated by periods, like 0.0.0.0 to 255.255.255.255.

The most common types are IPv4 and IPv6. Almost all 4.3 billion IPv4 addresses are in use, but there's a vast supply of IPv6 addresses, likely enough to never run out.

The DNS

IP addresses are stored as numbers in devices.

The Domain Name System (DNS) converts these numbers into names, making it easier for users to navigate the internet and name their network devices.

What Is a Static IP Address?

A static IP address is a constant address that doesn't change.

Internet Service Providers or ISPs typically give out static IP addresses for use by businesses and servers.

Once assigned, these addresses generally remain the same unless the device changes or the network is altered.

Usually, if you want to get a static IP address, you will have to pay extra. They can be both IPv4 or IPv6, but currently, permanent addresses are static IPv4 addresses.

What Is a Dynamic IP Address?

A dynamic IP address is one that changes periodically.

Dynamic IP addresses typically change when you restart your router or system and may be reassigned to other devices when not in use.

They are commonly used for home networks and individual users.

For example, your office likely uses a static IP address, while your personal computer uses a dynamic one.

Dynamic IPs are common because there aren't enough IPv4 addresses for every internet user to have a static one.

ISPs issue dynamic IP addresses temporarily using their Dynamic Host Configuration Protocol servers. This standard approach is used for consumer devices like PCs, smartphones, and tablets.

Other Types of IP Addresses

• Local or private

These IP addresses have a local reach and are used for private networks where devices can connect and share information securely within the private network.

• Public

These IP addresses have a global reach and are used to communicate with all users on the Internet, where all information is public and easily discoverable.

Static Vs. Dynamic IP: Which is Faster?

Static and dynamic IP addresses do not inherently differ in speed — both types of IP addresses offer similar performance in terms of network speed.

The primary difference lies in how the IP addresses are assigned and managed.

Static IP addresses remain constant, offering benefits for devices that require consistent, easy-to-remember IP addresses, such as servers or remote access setups.

Dynamic IP addresses, assigned by a DHCP server, can change over time, which is more common for everyday internet users and typically requires less manual configuration.

The speed of a connection is influenced more by factors such as the quality of the internet service, network congestion, and hardware performance rather than whether the IP address is static or dynamic.

Static IPs vs. Dynamic IPs in VPN Services

A VPN (Virtual Private Network) can provide both static and dynamic IP addresses, depending on the service provider and the specific plan you choose.

Some VPN providers offer a static IP address, which stays the same each time you connect.

This is useful for accessing services that need a consistent IP address, such as remote work/collaboration or secure networks.

Other VPN services provide dynamic IP addresses, which change with each session to enhance privacy and security by making it harder to track your online activities.

The choice between static and dynamic IP addresses ultimately depends on your specific needs and the features offered by the VPN provider.
