sslip.io is a Go-based DNS server that maps specially-crafted hostnames with embedded IP addresses (e.g. 127-0-0-1.sslip.io) to those IP addresses. It can be used as a public service or self-hosted on your own nameservers, including in air-gapped environments.
Use cases
- resolve hostnames with embedded ip addresses to those ips
- run a wildcard dns server for local development
- test webhooks without owning a domain
- serve sslip.io-style lookups on a custom subdomain
- run dns in an air-gapped environment
- self-host a nameserver with docker
When to choose
- you need wildcard DNS mapping IPs to hostnames without registering domains
- you want a lightweight, self-hosted alternative to xip.io/nip.io
- you need DNS resolution in air-gapped or isolated networks
When to avoid
- you need a general-purpose recursive DNS resolver
- you need full DNS zone management with record types beyond A/AAAA/NS/TXT basics
