How to Bring Your Own IP Range (BYOIP) to Cherry Servers

Cherry Servers understands that flexibility and control over your server and its operations is crucial to smooth operations. That’s why we permit our clients to bring their own IP address range to Cherry Server deployments, starting from /24, 256 IP addresses.

Please allow up to 24 hours after the process is complete as worldwide ISPs will require time to recognize the IP range.

#Instructions to Bring Your IP Range to Cherry Servers AS

For a smooth integration, we recommend that you first ensure that your IP prefixes are not blocked in public IP databases for suspected botnets or spamming. Blocked prefixes may be filtered by ISPs, leading to reachability issues.

To get started, please contact our dedicated support engineer team to inform them that you intend to bring your own IP range, and provide them with the required information according to the instructions below. This will help us assist you in expediently completing the process.

#1. Select a Cherry Servers Location

Choose the Cherry Servers data center you would like to bring your own IP range to, based on where your servers are deployed. You will need the related Autonomous System Number (ASN) to create a new route object, as well as a Route Origin Authorization (ROA). Cherry Servers region ASN are listed in the table below.

#2. Create Route Object and ROA Record

To establish routing with Cherry Servers, update your IP prefix through the Regional Internet Registry (RIR) or Internet Routing Registry (IRR) where it is registered. When creating an ROA for the intended IP prefix, use the Cherry Servers AS for the region you selected, and generate an ROA record.

If your IP range is provisioned through an IP renting service, they may offer the option to create a route object and ROA on your behalf through an easy-to-use panel.

#3. Create LOA Documentation

To authorize Cherry Servers to announce your IP range, we require a Letter of Authorization (LOA). This document confirms that we have your express permission, and acts as a safeguard for your IP against hijacking.

If you own the subnet, you will need to create the LOA with the following information:

• Date - the date that the LOA was signed and issued;
• Provider Information - the full legal name of the Internet Service Provider (ISP) or carrier being granted the authority to announce the IP space;
• Cherry Servers ASN - the Autonomous System Number (ASN) for the Cherry Servers region that will originate the routes;
• IP Information - The specific IP address range that the provider is authorized to announce;
• Authorization Statement - A clear statement that the owner of the IP range authorizes Cherry Servers to announce the specified IP range on their behalf;
• Owner’s Name - the full name of the individual or organization that owns the IP space;
• Owner’s address - These details must match the information registered with the relevant Regional Internet Registry (RIR);
• Signature.

If your IP range is provisioned through an IP renting service, you may have the ability to download an LOA for the subnet as a PDF file.

#4. Submit Your IP Prefix for Validation

Cherry Servers will need to verify the validity of your IP prefix to ensure compliance with security policies and network integrity. Please provide our dedicated support engineer team with the following information:

• The IP prefixes you wish to bring,
• ROA records for the IP prefixes,
• LOA documentation.

#5. Wait for Global Propagation

After submitting information to our engineer support team, please allow up to 24 hours for your IP range to become available. ISPs worldwide may take up to 24 hours to recognize the new subnet.

You can monitor the propagation of your announced prefix using tools such as:

• Hurricane Electric's BGP Toolkit – Provides visibility into your BGP routes across the internet;
• RIPEstat – Analyzes routing and ASN details for your prefix;
• BGPView – Monitors real-time prefix propagation and peer announcements.

Once complete, your IP prefix will be fully operational and available for use under the server announcing it.
