AS11251 — DSTL-2-11251
Network type: hosting
AS11251 announces 11 IPv4 prefixes covering 4,608 addresses and 7 IPv6 prefixes.
About this network
AS11251 (DSTL-2-11251) belongs to Disney Streaming Services, the Walt Disney Company subsidiary in New York City that builds and runs Disney's direct-to-consumer streaming platforms. Despite the low AS number, this is a recycled ASN: ARIN registered it to Disney in 2018.
What it's used for
The internet edge of a streaming technology company. RIS observes 19 IPv4 prefixes carrying 4,864 addresses, 12 IPv6 prefixes, and 13 observed neighbours. That combination is worth reading carefully, because the brand invites the wrong conclusion. Thirteen neighbours and under 5,000 addresses is an enterprise footprint, not a content-delivery network. Disney does not push Disney+ and ESPN+ video to viewers from this ASN at anything like the scale the name suggests. Mass video delivery rides commercial CDNs. What this space plausibly carries is the company's own edge, interconnect and service infrastructure, and the pack has no reverse DNS on it to say more precisely than that.
Almost every prefix RDAP resolved is registered to Disney itself, under DISNEY-DSS, DISNEY-DSS-2 and DISNEY-MNT. The one exception, 8.5.5.0/24, is registered to Level 3 Parent LLC: that is ordinary provider-assigned carrier space, not a third-party registrant, and it is not a leasing signal.
Notable
The IPv6 posture is much stronger than the IPv4 one, with 12 prefixes against 19 IPv4 routes: a modern greenfield network built when v6 was table stakes, rather than a legacy estate retrofitted. Most of the v6 sits in 2620:138::/32 (ARIN), but 2a0e:bbc0:8000::/48 is RIPE space, the footprint of a service that had to land in Europe as well as North America.
Interesting
The AS number is the trap here. AS11251 looks like an early-internet allocation, but the ARIN registration event is dated 1 February 2018 and the DSTL-2 org handle dates to November 2018, both modern. That timing is the corporate history: Disney took majority control of BAMTech Media in 2017 and renamed it Disney Streaming Services in 2018, exactly when this number and org record appear. Disney Streaming also holds AS22604.
