Summary
ARE-East River Science Park, LLC
business leased mixed us
ARSPL is the AS handle for ARE-East River Science Park, LLC.
What it's used for
- The address space carries a mix of corporate and third-party infrastructure, evidenced by netnames
ALEXANDR32-113,ALEXANDR92-232,COGENT-A,CC04, andRCN-BLK-6. - Reverse DNS entries such as
syn-047-045-038-064.biz.spectrum.comindicate the presence of Charter Communications business broadband services within the inventory. - The AS announces 2048 IPv4 addresses across 8 prefixes while maintaining 10 observed neighbours, a ratio that suggests a small-scale access or hybrid network rather than a large transit provider.
Notable
- Registrants do not uniformly match the announcer; seen registrants include Alexandria Real Estate Inc., Alexandria Real Equities, Cogent Communications, LLC, Charter Communications LLC, and RCN.
- The address inventory is fragmented, consisting of eight distinct /24 blocks sourced from different original holders, indicating a collection of leased or acquired space rather than a single contiguous allocation.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
9 upstream, 0 downstream and 9 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
