About this network

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-192-19 with registrant Avago 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 including 192.19.136.0/21 and 192.19.176.0/21.
• 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.
