An alternative to editing a hosts
file is to use the “Magic DNS” service https://nip.io/
nip.io is a magic domain name that provides wildcard DNS for any IP address. Say your LAN IP address is 10.0.0.1:
10.0.0.1.nip.io resolves to 10.0.0.1 (dot syntax)
192-168-1-250.nip.io resolves to 192.168.1.250 (dash syntax)
0a000803.nip.io resolves to 10.0.8.3 (hex syntax)
foo.bar.10.0.0.1.nip.io resolves to 10.0.0.1 (subdomains)
app-192-168-1-250.nip.io resolves to 192.168.1.250 (prefixes)
With this service, you can specify a public-looking domain that resolves to a private address.
In the Console, if your Redirect URI was (what you wish you had anyways):
http://192.168.1.1:8080/auth/google_oath2/callback
Replace it with:
http://192.168.1.1.nip.io:8080/auth/google_oath2/callback
“Redirect URIs” does not seem to accept wildcards, so the entire private ip-xip.io needs to be specified in the console.
