Summary

Netflix

United States of America · AI-generated

cdn streaming media business

NETFLIX-ASN is operated by Netflix Streaming Services Inc.

What it's used for

  • The address space carries Netflix's content delivery infrastructure, evidenced by netnames SS-CDN-4 on the 45.57.x.x blocks and DVD-NETFLIX on the 207.45.72.0/22 block.
  • The AS announces 3584 IPv4 addresses across 6 prefixes and 6 IPv6 prefixes, with only 1 observed neighbour, indicating a dedicated content delivery network rather than a transit or access provider.
  • Traffic from this AS consists of video streaming media and associated CDN endpoints for Netflix subscribers globally.

Notable

  • Registrants align with the announcer, listing Netflix Streaming Services Inc. for the 45.57.x.x prefixes and Netflix, Inc; Network Group for the 207.45.72.0/22 prefix.
  • The inventory is finely subdivided into small /23 blocks for the CDN space, consistent with internal corporate segmentation for content delivery nodes.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
