IPv6

DreamHost allows users to add IPv6 addresses to domains hosted in the panel. IPv6 has some advantages, one of which is that a much larger pool of IPs is available than IPv4, which is becoming outdated.

While there is a charge for adding an IPv4 address, there is no charge when adding an IPv6 as many addresses are still available.

To add an IPv6 address:

1. Navigate to the Manage Websites page.
2. Click the Manage button to open the Domain Settings page, which allows you to adjust various settings for your site.
   • If in Grid view, click the Manage button at the bottom of the website box.
   • If in List view, click the Manage button at the far right of your domain name.
3. Select the Hosting tab.
4. Scroll down to the Unique IP section.
5. Click the Manage button.
6. Select the IPv6 Settings tab.
7. Click the Add IPv6 Address Now button.

IPv6 addresses can be removed from the Hosting tab. Click the Cancel IPv6 button and then click the red Yes, remove button that subsequently appears.

There are a few ways to test if an IPv6 address is active and responding.

Ping the address

Run a ping command to your hostname. For example:

[server]$ ping6 example.com
PING example.com(example.com) 56 data bytes
64 bytes from example.com: icmp_seq=1 ttl=63 time=0.302 ms
64 bytes from example.com: icmp_seq=2 ttl=63 time=0.718 ms
64 bytes from example.com: icmp_seq=3 ttl=63 time=0.340 ms
64 bytes from example.com: icmp_seq=4 ttl=63 time=0.843 ms
64 bytes from example.com: icmp_seq=5 ttl=63 time=0.592 ms

--- example.com ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4009ms
rtt min/avg/max/mdev = 0.302/0.559/0.843/0.210 ms

You can also use an online tool to ping IPv6. For example:

• www.subnetonline.com/pages/ipv6-network-tools/online-ipv6-ping.php
• centralops.net/co/Ping.aspx

Run a dig command to check if the IP is resolving

[server]$ dig +short AAAA example.com
2607:f298:4:152::3d1:2cb7

If it’s resolving, you’ll see the IP address respond.
