About this network

GSHULLGR is the autonomous system for The Goldman Sachs Group, Inc.

What it's used for

• The address space carries internal corporate infrastructure, evidenced by netnames such as GOLDSACHS, GS-1, and GSCO-NETBLK-2, along with reverse DNS entries like mxe10.gsqatest.com.
• The AS announces 3840 IPv4 addresses across 14 prefixes while maintaining only 3 observed neighbours, a ratio that indicates a small, self-contained corporate estate rather than a transit or access provider.

Notable

• All registrants align with the announcer, consistently listing either "The Goldman Sachs Group, Inc." or "Goldman Sachs" across the inventory.
• The inventory is finely subdivided into 14 distinct prefixes, including a mix of legacy blocks like SPRINTLINK and modern allocations, reflecting site-by-site segmentation typical of a large financial institution.
