New on RIPE Labs - How many RIPE NCC ASN holders use RIPE Routing Registry?
by Mirjam Kuehne 28 Jan '11

28 Jan '11

[apologies for duplicates] Dear colleagues, It is often claimed that the Internet Routing Registry is not accurate and complete enough. Is this really the case? In a new article on RIPE Labs, we look at how many organisations that receive an Autonomous System Number from the RIPE NCC use the RIPE Routing Registry: https://labs.ripe.net/Members/mirjam/interesting-graph-how-complete-is-the-… The next step will be to find out how accurate this information is. Kind Regards, Mirjam Kuehne RIPE NCC
