PCH AS42 (AS42)

AS42 belongs to Packet Clearing House, a San Francisco non-profit founded in 1994, and it is one of the lowest autonomous system numbers still carrying production traffic. What it carries is DNS: root nameservers, the authoritative service for well over a hundred country-code top-level domains along with their government and military subdomains, the reverse-lookup zones, and the Quad9 recursive resolver. Almost none of it is for sale: hosting is pay-what-you-like for non-profit registries and free for developing-country ones.

That makes the case for having it in your building technical rather than commercial. Every answer for those zones that resolves locally instead of crossing an ocean is latency taken out of the first step of every connection your users make, and Packet Clearing House will interconnect with networks of any size, at public fabrics or on private cross-connects from 10 gigabit upward, provided you clear an operational bar rather than a commercial one: consistent announcements, BCP 38 filtering, and a staffed round-the-clock operations centre. It also runs route collectors at roughly a third of the world's public exchange points and publishes the raw data, which is where a good deal of what the industry knows about interconnection comes from.
