About this network

NFL1 is the larger of two autonomous systems registered to the National Football League at 345 Park Avenue, New York. Its sibling is AS6209.

What it's used for

• Corporate, media and production networking for the league — offices, broadcast and content operations, and league-run digital systems.
• Announces roughly 5,600 IPv4 addresses, mostly as /21s, several times the footprint of its sibling ASN.

Notable

• This is a sports league running its own enterprise network. The address space carries the NFL's own traffic; it is not a hosting, transit or eyeball network and none of it is resold.
• Reverse DNS is largely unpublished across the space, which is typical of a private corporate network that has no reason to advertise its internal structure.

Interesting

• Holding two low, adjacent AS numbers is unusual for a non-technology company — a reminder that in the 1990s, when these numbers were handed out, any organisation multihoming to more than one provider needed its own ASN, sports leagues included.
