This is a fork of http://nip.io with some neat changes.
Dead simple wildcard DNS for any IP Address
nip.io allows you to map any IP Address in the following DNS wildcard entries:
It works with Dashes -, perfect for wildcard TLS certs:
10-0-0-1.nip.io maps to 10.0.0.1
app.10-0-0-1.nip.io maps to 10.0.0.1
customer1.app.10-0-0-1.nip.io maps to 10.0.0.1
As well as Dot .:
10.0.0.1.nip.io maps to 10.0.0.1
app.10.0.0.1.nip.io maps to 10.0.0.1
customer1.app.10.0.0.1.nip.io maps to 10.0.0.1
See https://github.com/resmo/nip.io/blob/master/src/backend.conf.example for an example config-
Hint: See the static CNAME _acme-challenge=xyz.auth.example.com. in the example, use it with https://github.com/joohoi/acme-dns for free Let's Encrypt TLS certs.
