Hey folks,
The URL in question is from an unsubscribe link in an opt-out-only
unsolicited marketing email from IBM (no business has ever been

Hello,
if we are talking about a list of DO IP prefixes, why not rely on
routing information with bgpq4 [1] instead?

$ bgpq4 AS-14061 -A6R128 -F '%n/%l\n' | wc -l

Should be more reliable than a manually updated txt file.

which makes this a good UI choic

Dear list,
looking for a human at sorbs.net, online ticketing is completely
