Generated on 13 Mar 2026

[IP addresses](https://www.digitalocean.com/community/tutorials/understanding-ip-addresses-subnets-and-cidr-notation-for-networking) let machines communicate across a network. DigitalOcean Droplets are assigned IPv4 addresses by default. Enabling IPv6 on a Droplet gives you access to its 16 additional IPv6 addresses.

[IPv6 Features](https://docs.digitalocean.com/products/networking/ipv6/details/features/index.html.md): IPv6 is the most recent version of the IP protocol. In addition to improvements on the protocol itself, IPv6’s massive increase in available address space makes it less vulnerable to brute force–style security exploits, like ones which scan an entire address space searching for vulnerabilities.

[IPv6 Pricing](https://docs.digitalocean.com/products/networking/ipv6/details/pricing/index.html.md): IPv6 support is available for Droplets at no additional cost.

[IPv6 Availability](https://docs.digitalocean.com/products/networking/ipv6/details/availability/index.html.md): IPv6 is available for Droplets in every region.

[IPv6 Limits](https://docs.digitalocean.com/products/networking/ipv6/details/limits/index.html.md): Limits and known issues for IPv6.
