About this network
The AS handle UHS-088 is held by Universal Health Services.
What it's used for
- The address space carries corporate infrastructure for a healthcare provider, evidenced by reverse DNS entries like sftptest2.uhsinc.com and 64.uhshost.uhsinc.com.
- The inventory consists of 1024 IPv4 addresses across 4 prefixes, with only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
Notable
- Registrants for the 12.3.0.0/16 space are UHS OF DELAWARE INC, while the 50.237.0.0/16 and 50.238.0.0/16 prefixes are registered to Comcast Cable Communications, LLC, suggesting a mix of owned and leased or historically allocated space.
- The address inventory is finely subdivided into four /24 blocks, consistent with internal site-by-site segmentation for a large corporate entity.
