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has some advantages, one of which being that there is a much larger pool of IPs available than IPv4 which is becoming outdated.

dreamhosters.com subdomains and sites on DreamPress cannot add Unique IP addresses.

Adding an IPv6 address

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

To add an IPv6 address:

  1. Navigate to the Hosted Domains page.

  2. Click the UniqueIP link under your domain.
  3. Select the IPv6 Settings tab.
  4. Click the Add IPv6 IP Now button to add an IPv6 address to your domain.
    After adding the IPv6 address, you are redirected back to the 'Hosted Domains' page where you'll see the new address assigned to the designated domain or subdomain:
    IPv6 record
  5. To remove the IP, select the red ‘X’ next to the IP.

Testing an IPv6

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:

Run a dig command to check if the IP is resolving

[server]$ dig +short AAAA example.com

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