[AusNOG] Peering For Porn

[Seamus Ryan]

One of the larger conglomerates , sometimes referred to as the "Pornhub Network", uses a range of CDN's worldwide.

I have ascertained the above network uses two CDN's primarily (there may be more I am unaware of, can't be certain).
The two CDN's in question appear to be Reflected (reflected.net), which looks to just be resold Level 3 CDN. In most cases this content is being served out of the USA (West Coast)... at least that is where I am being sent.
The other, which appears to be used more often by the above adult network, is LLNW. In some cases content is being served out of Sydney, while in other cases it is being pushed to Tokyo. This appears to be on a site by site basis. Some of the "sister" websites are primarily served out of Tokyo, while others (possibly the more popular ones?) are being pushed right into Sydney.

I vaguely recall "PornHub" ran their own CDN may years ago, check your resolvers for dns names such as "phncdn.com" as it looks like the DNS names are still used to serve up most content. You may be able to figure out roughly what type of CDN hits you are getting and who you could possibly peer with.

Granted, this is only one small piece of the puzzle. With a little research you can probably figure out which networks are best suited to your clients' "needs" :)

Cheers,
Seamus

Interesting question. I think two of the big ones are on any2. I kind of assumed they would be on akamai (or like) but perhaps not. I wonder if there is a storm around content distribution of unclassified content locally. Making it just to hard. We are mainly a Business ISP but we still see a fair amount of that type of material I would wager.

Hi James,

I think Redtube is cached locally from memory, may want to refer your customers to that as the preferred source of pornographic love :)

Hey Noggers,

With most of the "legit" content providers (e.g. Google, Akamai, Apple, Amazon etc) peering at one or more of the local peering exchanges what is the situation with the major porn sites? We know this type of traffic makes a large proportion of residential ISP traffic. Is there any way to get this content without it taking up IP transit?
