About this network
UTMDACC is the University of Texas M.D. Anderson Cancer Center, the comprehensive cancer hospital and research institution in the Texas Medical Center in Houston. It is part of the University of Texas System: a treating hospital, a research enterprise and a degree-granting academic institution in one organisation.
What it's used for
The institution's own campus network. RIS shows 65,792 IPv4 addresses, dominated by a single 143.111.0.0/16, with 4 observed BGP neighbours and no IPv6 in the table. A /16 behind four peers is an end-site, not a carrier — the address space serves clinical, research and administrative systems on one very large campus rather than transiting anyone else's traffic. Reverse DNS confirms the character of it: 143.111.5.5 answers as mdavpnr.mdanderson.org, a remote-access concentrator, and 143.111.86.133 as nursg09pub-133.mdacc.tmc.edu — a nursing-unit host under the institution's Texas Medical Center domain. Clinical endpoints, staff access and research computing, all first-party.
Notable
Every announced prefix registers to MD Anderson itself under MDANET netnames, including the smaller 192.108.242.0/24. There is no third-party registrant anywhere in the inventory and no reason to look for one. The /24s that appear alongside the /16 are more-specifics of space the institution already holds, announced separately — a routine traffic-engineering or multihoming choice, not separate inventory.
Interesting
The reverse DNS spans two domains, mdanderson.org and mdacc.tmc.edu, reflecting the institution's dual identity: a hospital brand facing patients and an academic one inside the Texas Medical Center's .edu namespace.
