United States of America · AI-generated

The AS handle ADAGE-CAPITAL---ASN is held by Adage Capital Partners, LLC.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netnames LVLT-ACPL-8-8-21-83 and ECIN-65-244-59-0 and reverse DNS entries pointing to ezecastlehosting.com.
  • The AS announces 512 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access provider.

Notable

  • Registrants align with the announcer, listing Adage Capital Partners, LLC and Adage Capital for the respective prefixes.
  • The inventory consists of two /24 blocks, one originally associated with Level 3 Communications (LVLT) and the other with ECIN, indicating a consolidated corporate address space.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
