# IPv6 How-Tos

Generated on 19 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.

## Getting Started

[How to Enable IPv6 on Droplets](https://docs.digitalocean.com/products/networking/ipv6/how-to/enable/index.html.md): Enable IPv6 on a Droplet to gain access to its 16 configurable IPv6 addresses.

[How to Enable Additional IPv6 Addresses](https://docs.digitalocean.com/products/networking/ipv6/how-to/configure-additional-addresses/index.html.md): Each Droplet is allotted 16 IPv6 addresses, one of which is configured automatically. Configure additional IPv6 addresses within this range to use different addresses for different purposes.

[How to Disable IPv4 and Only Use IPv6](https://docs.digitalocean.com/products/networking/ipv6/how-to/disable-ipv4/index.html.md): Disable IPv4 to rely solely on IPv6.
