Summary
Broadcom
semiconductor corporate business
AVG19637 is held by Avago Technologies U.S. Inc., the former name of Broadcom Inc.
What it's used for
- The address space is registered under the netname
AVG-192-19with registrantAvago Technologies U.S. Inc., indicating a corporate internal network rather than public customer access. - The AS announces 24,576 IPv4 addresses across 60 prefixes and 9 IPv6 prefixes, while maintaining 27 observed neighbours; this ratio of moderate address space to significant peering suggests a large-scale corporate estate with multiple uplinks for redundancy and connectivity.
Notable
- All sampled registrants match the announcer, consistently listing
Avago Technologies U.S. Inc.for prefixes including192.19.136.0/21and192.19.176.0/21. - Avago Technologies changed its name to Broadcom in January 2016 following its acquisition of Broadcom Corporation, meaning this AS now represents the infrastructure of the merged semiconductor entity.
- The inventory consists of finely subdivided blocks, including numerous /23 and /24 prefixes, which is characteristic of site-by-site segmentation within a large corporate network.

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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
