## What it is
nsupdate.info is a free dynamic DNS service and the self-hostable Django/Python software that powers it. It accepts dynamic DNS updates via the dyndns2 protocol and forwards them to nameservers using RFC 2136 DNS UPDATE.

## Use cases
- host my own dynamic dns service on my server
- keep my home ip address mapped to a domain name
- update dns records from a router using dyndns2
- dynamic dns for ipv6 with changing prefixes
- update multiple hosts in my lan from one updater
- self-hosted alternative to dyndns providers

## When to choose
- you need dynamic DNS with IPv4 and IPv6 support and TLS
- you want to self-host a dyndns service compatible with routers and update clients
- you want to forward updates to third-party DNS services or RFC 2136 nameservers like BIND or PowerDNS

## When to avoid
- you need a DNS nameserver itself - it only updates existing nameservers
- you need a simple client-only updater without a server component
- you need managed DNS hosting rather than dynamic updates
