How to Request an IPv6 Address Block

Overview

We provide IPv6 address blocks to customers who require IPv6 connectivity on their servers. By default, each server is eligible to receive a /64 IPv6 block, which provides an enormous range of addresses suitable for virtually any use case — from single-service hosting to complex multi-service deployments.

If you'd like an IPv6 block assigned to your server, simply submit a request through the customer portal.

Who Can Request an IPv6 Block?

Any customer with an active server on our network is eligible to request a /64 IPv6 block. Eligibility requirements:

• You must have an active server with us
• The server must be on a network that supports IPv6 (if you are unsure, our support team can confirm)
• One /64 block is provided per server

Note: IPv6 blocks are assigned per server. If you have multiple servers and need IPv6 on each, please submit a separate request per server or note all servers in a single ticket.

What is a /64 Block?

A /64 IPv6 block is the standard allocation size for a single network segment. It contains 18.4 quintillion (2⁶⁴) individual IPv6 addresses, giving you far more flexibility than a typical IPv4 allocation.

Example /64 block:

2001:db8:abcd:1234::/64

This means all addresses from 2001:db8:abcd:1234:0000:0000:0000:0000 through 2001:db8:abcd:1234:ffff:ffff:ffff:ffff are within your block.

What You'll Need

Before submitting your request, have the following information ready:

That's it — we handle the block assignment and routing on our end.

How to Submit a Request

1. Log in to the customer portal at your provider's portal URL.
2. Navigate to Support → Open a Ticket (or click New Ticket).
3. Select the department Support.
4. In your ticket, include the following:
   • The server hostname or ID you want the IPv6 block assigned to
   • A brief note that you are requesting a /64 IPv6 block
   • Your intended use (optional but helpful)
5. Submit the ticket.

Example Ticket Request

Hi, I'd like to request a /64 IPv6 block for my server.

Server: server01.yourdomain.com (Server ID: 12345)
Request: /64 IPv6 block assignment
Intended Use: Email hosting

What Happens Next?

Once your ticket is received, our team will:

1. Allocate a /64 block from our IPv6 pool and assign it to your server
2. Configure routing so the block is reachable over our network
3. Reply to your ticket with the assigned block details, including:
   • Your assigned /64 prefix
   • Gateway information
   • Any configuration notes specific to your server or OS

Processing Time

IPv6 block requests are typically fulfilled within 1 business day. You will be notified via your support ticket once the block has been assigned and is ready to use.

Configuring IPv6 on Your Server

After your block is assigned, you will need to configure IPv6 on your server. The steps vary by operating system. Below are general starting points — your ticket response will include any environment-specific guidance.

Linux (Ubuntu/Debian — Netplan example):

network:
  version: 2
  ethernets:
    eth0:
      addresses:
        - 2001:db8:abcd:1234::1/64
      gateway6: 2001:db8:abcd:1234::fffe

Linux (RHEL/CentOS — ifcfg example):

IPV6INIT=yes
IPV6ADDR=2001:db8:abcd:1234::1/64
IPV6_DEFAULTGW=2001:db8:abcd:1234::fffe

Windows Server:
Navigate to Network Adapter Properties → Internet Protocol Version 6 (TCP/IPv6) → Properties, and enter your assigned IPv6 address and gateway manually.

Replace the example addresses above with the actual values provided in your support ticket response.

Verifying IPv6 Connectivity

Once configured, you can verify your IPv6 connectivity with the following commands:

Linux / macOS:

ping6 google.com

or

curl -6 https://ipv6.google.com

Windows:

ping -6 google.com

You can also check your assigned address is responding:

ping6 2001:db8:abcd:1234::1

Frequently Asked Questions

Can I request more than one /64 block per server?
Our standard allocation is one /64 per server, which provides billions of usable addresses. If you have a specific requirement for additional blocks, please explain your use case in your support ticket and our team will review it.

Can I request rDNS (PTR records) for addresses in my IPv6 block?
Yes. Once your block is assigned, you can request PTR records for any addresses within it. See our related article: How to Request Reverse DNS (rDNS) for Your IP Address.

Will IPv6 replace my existing IPv4 address?
No. Your IPv4 address remains unchanged. IPv6 is additive — your server will be dual-stack, accessible over both IPv4 and IPv6.

Do I need to update my firewall rules?
Yes. If you have a firewall configured on your server, you will need to add IPv6 rules equivalent to your existing IPv4 rules. IPv4 firewall rules do not automatically apply to IPv6 traffic.

Is there an additional cost for an IPv6 block?
IPv6 /64 blocks are provided complimentary to customers on supported plans. Please refer to your service agreement or contact support if you have billing questions.
