How to Buy Public IP Addresses

Larus Team 2023-10-13 06:38:02 BUY IP

There are a number ways buy a public IP address: from an ISP, RIR, or through an IP address broker. First, let's look into the basics of public IP addressing.

What is a Public IP Address?

A public IP address is the address that identifies your network over the Internet.

In contrast, a private IP address is assigned by your routers to specific devices within your home or office network.

A public IP address may also be referred to as "external IP address."

You can get a public IP address from your Internet Service Provider (ISP) or from a Regional Internet Registry (RIR).

Types of Public IP Address

The two main types of public IP addresses are dynamic and static.

Static IP addresses are preferred by businesses as they offer higher levels of stability and security. Plus, they are likely to be more efficient as static IP addresses can be used exclusively.

If you are a business owner or a network administrator looking to get these benefits, you might want to consider how you to get a public IP address.

Below are these general steps.

How to Buy Public IP Address

Generally, you'll need the following to complete your IPv4 purchase: an IP address bock, an anonymous system number, and network configuration. These are the steps:

1. Get an IP Address Block

To obtain an IP address block, you'll need to consider the size of your organization. If you're a big firm, you can request one from Regional Internet Registries (RIRs) or major Internet Service Providers (ISPs).

If your RIR or ISP is not able to provide you with the IP addresses you need, you can go through a broker to help you get the address space you need.

IP brokers are also ideal for smaller businesses as they offer more flexible options.

For Larger Organizations: You can reach out to organizations like APNIC or ARIN. For IPv4, you'll get a block with 256 addresses, known as /24. In IPv6, it's a /48 block.

For Smaller Organizations: You can work with a reputable broker to purchase the address block you need.

2. Secure an ASN (Autonomous System Number)

An Autonomous System Number (ASN) is like a unique code for your network. You need it to connect to the Border Gateway Protocol (BGP), which acts as an internet traffic controller. You can request an ASN from IP registries like APNIC or ARIN. It helps direct traffic to your network and separates it from other internet networks.

3. Get BGP Transit Service

Border Gateway Protocol (BGP) is a tool that lets your network announce its address block to the internet. To use BGP, you'll have to get in touch with an Internet Service Provider (ISP) and buy BGP transit service. This service links your network to the broader internet through the ISP's network.

4. Set Up Your Network

Once you have an ASN and subscribe to BGP transit service, you'll need to configure your Wide Area Network (WAN) router to connect to the BGP. Your WAN router will establish connections with the ISP's router. This will allow you to share your address block information with the internet.

5. Connect your IP Address Block over the Internet

To make your address block accessible on the internet, use BGP to announce it to your ISP. Once your ISP receives this announcement, it will connect your network across the internet, allowing data to flow to and from your network.

Why Having a Fixed Public IP Address Is Beneficial

1. Hosting Services

With a static public IP address, you can directly host services like websites, email servers, and VPN servers on your network. This gives you more control and reliability for these services.

2. Bypassing ISP Filters

A static IP can help you bypass internet service provider filters because it's often associated with business-grade internet connections, which typically have fewer restrictions.

3. Professional Image

Having a static IP can make your organization appear more professional to other businesses and individuals. It signals that you have a dedicated online presence.

Factors to Consider

1. Cost

Maintaining a static public IP address can be pricier than using a dynamic IP address from your ISP. Be sure to think about your budget and needs before making a decision.

2. Technical Expertise

Setting up your network and working with BGP requires technical know-how. Ensure your team or staff have the right skills to handle these tasks effectively.

3. Security Responsibilities

With your own IP address, you're responsible for securing your network and the IP address itself. This means implementing strong security measures to protect against online threats and vulnerabilities.

Closing Thoughts

Purchasing a public IP address can be a complex process. If you need professional help, you may contact a reliable IPv4 broker like Larus. This will save you time and ensure that you set up your public IP address efficiently and correctly.
