Summary
Asac Comunicaciones
business msp it-services
ASACAS01 is operated by Asac Comunicaciones S.L., an IT consulting and managed service provider based in Asturias, Spain.
What it's used for
- The address space carries static IP endpoints for enterprise and public sector clients, evidenced by reverse DNS entries such as
customer.static.ccgg.telefonica.netandstaticIP.cloud4b.net. - The AS announces 4,352 IPv4 addresses across 8 prefixes and 2 IPv6 prefixes, maintaining 5 observed routing neighbours; this ratio indicates a business network providing connectivity for specific client sites rather than a large-scale residential access network.
- Traffic consists of web and API endpoints, office workers, and managed infrastructure for public sector and enterprise customers, consistent with the operator's role as an MSP offering software development, security audits, and network management.
Notable
- Registrants for the majority of prefixes are Asac Comunicaciones S.L., while the largest block
154.58.16.0/22is registered to Cogent Communications, LLC, and other blocks list NEMESYS ABUSE TEAM or VODAFONE ABUSE, reflecting historical allocations or leased space. - The inventory is a mix of /22, /23, and /24 blocks, with the largest allocation being the Cogent-registered /22.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-30, 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 1,849 prefixes, as published 2026-10-30. 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.
