Altering hostname-IP mapping within a browser
Solution 1:
In Chromium, you can use the --host-resolver-rules option to specify a list of mappings.
For example:
$ chromium \
--user-data-dir=/tmp/some-temp-dir \
--host-resolver-rules='MAP host1.example.com 127.0.0.1, MAP host2.example.com 127.0.0.1'
Solution 2:
I found a solution here that works for one IP on a per-Firefox-profile basis.
- Navigate to
about:config. - Set
network.dns.forceResolveto e.g.127.0.0.1
