I was wondering if anyone had a direct contact at level 3 who deals with their IRR database, since my queries logged with them on Saturday to both noc@ and abuse@ have gone unanswered.
I have just taken a look at the following:
whois -h whois.radb.net \!gAS11908 and there is a *HUGE* amount of IP space registered in the Level3 IRR database that is propagating to the other databases that clearly does not belong to AS11908. (Beyond the initial prefix of ours that noticed).
