The Hamachi VPN software hasn't been abandoned but continues to be made available under LogMeIn brand still using the netblock for it's addresses.<br /><a href="" rel="nofollow"></a><br /><br />Another similar product using the addresses in the same block is Comodo EasyVPN<br /><a href="" rel="nofollow"></a><br /><br />In both cases I've tried asking the companies what they intend to do now that the block has been assigned to RIPE but I've not had any official reply so far.
