Summary
DSCI Corporation
telecom business isp us
DSCI is the AS handle for DSCI Corporation, a telecommunications provider based in Waltham, Massachusetts.
What it's used for
- The address space carries business static IP services, evidenced by reverse DNS entries such as
ne.business.static.dsci-net.comand netnames likeDSCI-BLK-2andDSCI-BLK-3. - With 6912 IPv4 addresses announced across 16 prefixes and only 1 observed neighbour, the ratio indicates an access or eyeball network rather than a transit provider.
Notable
- Registrants are consistent with the announcer, primarily listing
DSCI CorporationandDSCI, LLC, with one legacy prefix registered toMV Communications, Inc.and another toPacket Engineering. - The address inventory is finely subdivided into /22, /23, and /24 blocks, suggesting internal segmentation for different service tiers or geographic sites.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
