Summary

NCTA - The Internet & Television Association

United States of America · AI-generated

association industry business us

The AS handle NCTA-WASHINGTONDC is held by NCTA - The Internet & Television Association.

What it's used for

  • The address space carries the association's internal network, evidenced by the netname NCTA-209-1 and registrant National Cable & Telecommunications Association.
  • The inventory consists of 256 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained corporate or organizational network rather than a transit or access provider.

Notable

  • The RDAP registrant National Cable & Telecommunications Association aligns with the AS holder, reflecting the organization's historical name prior to its rebranding.
  • NCTA is the trade association for the US cable industry, formerly known as the National Cable & Telecommunications Association, which explains the registrant name in the registry data.
  • The address inventory is minimal, consisting of a single /24 block and a single /48 IPv6 prefix, typical for an industry group's administrative presence.

Reputation

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
