About this network

EGINTERLINK — the network of Grady Memorial Hospital in Atlanta, Georgia, the flagship facility of Grady Health System and one of the largest public safety-net hospitals in the southeastern United States.

What it's used for

• Enterprise connectivity for a hospital campus: clinical systems, medical imaging, administrative IT, and staff access.
• Announces a handful of /24s carved out of a legacy 138.33.0.0 allocation plus a 192.35.x block.

Notable

• A hospital, not a service provider — the address space serves the institution itself rather than downstream customers.
• The ASN was registered with ARIN in April 1995, and the org record predates it further, so this is a genuinely early institutional allocation rather than a recycled number.
