AS10717 SCHOLASTIC

SCHOLASTIC is the corporate network of Scholastic Inc., the New York children's book and educational-media publisher (Harry Potter's US publisher, Clifford, the school book fairs and book clubs). Despite the name, this is a publisher's enterprise AS, not an education or research network.

What it's used for

RIS sees 6 announced IPv4 prefixes carrying 1,792 addresses, no IPv6, and only 3 observed neighbours. That combination is the signature of a corporate edge, not a service provider: a network selling transit or hosting at this size would show tens or hundreds of BGP neighbours, because peering breadth is what such a business is made of. Three neighbours means a couple of upstream carriers and a multihomed office/data-centre footprint.

The announced space is a contiguous run inside 199.19.136.0 through 199.19.143.0, plus a single outlying 208.205.75.0/24. Roughly 1,800 addresses is enough for corporate egress, mail, VPN concentrators and a modest set of public-facing services, and far too little to run a consumer product at Scholastic's reach. The customer-facing web properties are almost certainly served from commercial CDN and cloud platforms, as they are for most publishers of this era.

Notable

Scholastic holds a second, higher-numbered ASN as well, [AS14199](https://asn.ipinfo.app/AS14199) — a common pattern where a company picks up an extra number through an acquisition or a second site rather than renumbering.
