enterprise hosting edge legacy

YAHOO-DNB is a small Yahoo network. It is one of several autonomous systems the

company runs to carry its own services; Yahoo's bulk traffic rides other, much

larger ASNs.

What it's used for

  • Serving Yahoo's own web properties and supporting infrastructure. Reverse DNS on the range resolves under yahoo.com, with router names marking it as edge networking equipment.

Notable

  • Content-provider infrastructure rather than a hosting company: you cannot buy space here, and the addresses front Yahoo's services rather than third-party customers.
  • Deliberately small. Only three IPv4 /24s plus an IPv6 /48 are announced, around 768 addresses, which points to a single site or edge point of presence rather than a full data-center footprint.
