When IDNs (Internationalized Domain Names) were being introduced on the Internet in 2000 to 2001, internet entrepreneur Gregg N. Ostrick of GNO, Inc. was researching and registering specific key-word Japanese-character domain names. At that time, Ostrick discovered that various other Unicode special characters were also allowed to be registered as dot-com domains, along with Japanese Kanji and other non-English-character domain names.
In April of 2001, Ostrick registered several special-character domain names, including the Unicode Airplane, defined by its Unicode codepoint U+2708, in the Unicode Block “Dingbats,” with its official name as the “AIRPLANE,” established in Unicode 1.1 in 1993. The punycode domain name xn--3bi.com specifically refers to the single Unicode “AIRPLANE” character with the Unicode codepoint U+2708.
