As well as 62.0.0.0/8 there is 88.0.0.0/8 (originated by AS13064, with upstreams of AS13237 (LambdaNet) and AS 8447 (Telekom Austria)

Unlike 62.0.0.0/8, which is being announced as a stable announcement (and has AS 1299 (Telianet) as its upstream, 88.0.0.0/8 is being announced for periods of 30 seconds to 1 minute.

Last time we saw this short announce behaviour it was a spammer using the "vacant" addresses in the /8 block to generate spam in short bursts. I have no data on what is going on with 88.0.0.0/8

Here's what I see in terms of recent BGP activity for 88.0.0.0/8: http://88.0.0.0.8.potaroo.net and for 62.0.0.0/8: http://62.0.0.0.8.potaroo.net
