Hmm since I used to regularly buy everyone a beer after the meeting finished, perhaps I should just do that again and this time I'll just sit in the meeting happily taking calls all day long. Forfeit accepted! Steve Regards Nic ;-)

It would also be useful to be able to run resolver scans via ASN or larger block reports too. Limited to a /22 takes a fair old while.
