Hi Jack,

As OVH is a data centre, I find that extraordinary if eyeballs were the cost. VPN's may be popular but that seems excessive. Probably bots of some sort, scraping the internet.

Hi all!

I'm working on our IPv6 and DNSSEC adoption report for Canada and the data I use comes largely from APNIC (https://stats.labs.apnic.net/dnssec/CA) and (https://stats.labs.apnic.net/ipv6/CA).

Labs.APNIC has a pretty cool system to measure this kind of stuff by deploying specially crafted google ads, see "How Big is that Network?" https://labs.apnic.net/?p=526, and APNIC is able to assess the population behind a network based on ad placement distribution. See https://stats.labs.apnic.net/cgi-bin/aspop?c=CA for Canada.

The question I have is why does OVH come #6 with an estimated population of 1,480,927 behind its ASN? Remember these are actual placement of ads. Should I count those users as part of my stats?

Right, forgot to mention, it's population, not IP addresses, the average is 2.2 person / household in Canada I believe.

I have one IPv4 and five users in my household...

Hi, OVH ISP uses a slightly weird set-up: - separate AS for residentian IPv4 ranges. That AS is only seen in GRT via OVH main AS. - IPv6 is provided from the "main pool", advertised by the main AS. And yes, their hosting business hosts tons of VPNs (on VPS or dedicated servers) which are also used by a number of french users in order to get decent internet performance (for the case when their ISP does saturate transit - which is every day 17h-24h).
