Handy online tools

Tools for various uses.

icanhazip.com
Serves current IP address in plain text, which is the only content of the entire page. The FAQ for this page, and several other similar pages, is at [//major.io/icanhazip-com-faq/ major.io].

Amazingly simple webmail server, particularly useful for testing user setups of packages. Also great for creating throwaway email addresses when creating online accounts without revealing a legitimate email address.
