Thought I'd try accessing 8ch using its IP address, in case it is forcibly delisted from DNS. (ICANN is suspect, having been "freed from US government oversight" by the Hussein administration, in that administration's waning days). That does not work (see attached.) I assume adding it to the HOSTS file will work, as accessing 8ch.net that way will be transparent to any process checking for a valid Host header.

Note: 8ch.net currently resolves to 104.18.104.234
