IPv6 support is provided at no cost.
IPv6 is available for Droplets in every region.
SMTP traffic over IPv6 is blocked at the network level.
IPv6 communication requires that IPv6 is enabled and configured at both ends of the connection, and not all ISPs offer IPv6 addresses for customers, so you might not be able to use the an IPv6 address directly from your local machine.
We support a maximum of 16 addresses (a subnet mask of
/124) per Droplet. Additional addresses are not currently available.
If the name of an IPv6-enabled Droplet is a FQDN, a PTR record will be automatically generated only for the first IPv6 address assigned to the Droplet, not to all 16 addresses available.
It’s not possible to enable IPv6 on Droplets created from custom images.
