In some cases it may be useful to override the IP address what a hostname resolves to, for example, when developing an application that has been deployed locally. Any IP addresses set up here will override resolution from DNS server.

You can use wildcards in you hostnames, for example:

  • * matches to any hostname
  • *.example.com matches to any subdomain of example.com
  • ?.example.com matches to any one letter subdomain of example.com

Note that the first matching hostname resolution will be used.
