Summary

United States of America · AI-generated

cloud hosting business infrastructure

The AS handle SKYTAP-TUK is held by Kyndryl.

What it's used for

  • The address space carries cloud infrastructure, evidenced by reverse DNS entries such as 199-204-221-254.cloud.skytap.com and netnames including SKYTAP-DA1, SKYTAP-DA2, and SKYTAP-DA3.
  • The AS announces 8,192 IPv4 addresses across 12 prefixes with 5 observed neighbours, indicating a focused infrastructure footprint rather than a large-scale access or transit network.
  • Traffic from this AS consists of cloud platform endpoints and API services, reflecting Kyndryl's business in providing cloud uplift and hybrid cloud management solutions.

Notable

  • Registrants align with the announcer, with most prefixes registered to Kyndryl or Kyndryl, Inc., while one prefix (76.191.118.0/23) retains the legacy Skytap, Inc registrant.
  • Kyndryl acquired Skytap in 2024 and integrated its capabilities under the Cloud Uplift brand, explaining the mix of legacy Skytap and current Kyndryl identifiers in the registry data.
  • The inventory is finely subdivided into multiple /23 and /24 blocks, consistent with an internal corporate estate segmented by data center or service tier.

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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
