Available Public Wildcard DNS Domains pointing to localhost (127.0.0.1)

It turns out that some kind hearted people already set up wildcard domains for you already. You can use any domain below and/or any subdomain of these and they currently resolve to 127.0.0.1 but could switch at any time to resolve somewhere else. Here's the list of ones I know about. Let me know if there are more!

• localhost - It will always works. Do you know why? I hope so.
• [*.]fuf.me - Managed by @fidian; it will always point to localhost for IPv4 and IPv6
• [*.]fbi.com - 👏 👏 👏 👏 👏
• [*.]localtest.me
• [*.]127-0-0-1.org.uk
• [*.]vcap.me
