m

Welcome to the widest ASCII subdomain on the Internet.

m is the widest ASCII character allowed in domain names. Domains are effectively limited to 253 visible characters, so this domain is of length 58 + 1 + 63 + 1 + 63 + 1 + 63 + 1 + 2. .mx is the widest 2-character TLD that is easily registerable, which allows for extra ms in the subdomain.
