Our data shows that only 24% of user-encountered networks have a NAT that supports UPnP management (we successfully create a port mapping). That's across the Windows 7 and 8 population. That's unfiltered, so it will include hits from corporate environments, hot spots and such, etc.
I feel pretty good about "infering" that the number is residential networks is around 35%, looking at the top-of-the-line number and looking at other population metrics we collect. Nowhere near 80% :(. Sometimes a home router "supports" UPnP, but it's not activated by default. -----Original Message----- From: ipv6-ops-bounces+christopher.palmer=microsoft....@lists.cluenet.de [mailto:ipv6-ops-bounces+christopher.palmer=microsoft....@lists.cluenet.de] On Behalf Of [email protected] Sent: Friday, October 11, 2013 12:12 AM To: [email protected] Subject: SV: Microsoft: Give Xbox One users IPv6 connectivity I don't have numbers for other markets, but in Norway I would say more than 80% have UPnP enabled gateways. At least the ISP I work for have provided customers with UPnP enabled gateways the last 7+ years. Most devices I can see in the Norwegian market (online and physical stores) have support for UPnP. But not to derail the discussion to much. Even with UPnP enabled, there are apparently very different ways to enterpete how to use UPnP. Some clients fail misserably if they dont get the port they seek, some release the port as soon as it has been granted (older version of microsoft messenger did this, caused a lot of cpu usage on the gateways). Some clients do not understand that they have a port, and proceede to the next port and then use up all ports on the gateway. -Erik Taraldsen Telenor ________________________________________ Fra: [email protected] [[email protected]] på vegne av Mikael Abrahamsson [[email protected]] Sendt: 11. oktober 2013 06:50 To: Christopher Palmer Cc: [email protected] Emne: RE: Microsoft: Give Xbox One users IPv6 connectivity On Thu, 10 Oct 2013, Christopher Palmer wrote: > The thing about protocols like UPnP - the vendors who would ignore an > IETF recommendation are likely to be the same vendors to skip out on > making an adequate UPnP stack.

My belief has been that most people today who care about anything more than web surfing would have a decently new gateway (less than 3-5 years old) and that this would support UPnP. I don't have any numbers so I would like to know more :) -- Mikael Abrahamsson email: [email protected]
