Summary
Eli Lilly and Company
enterprise legacy
Autonomous System 4249 (LILLY-AS) is registered to Eli Lilly and Company, the
pharmaceutical manufacturer headquartered in Indianapolis, Indiana.
What it's used for
- Corporate network connectivity for Lilly's global operations: offices, research sites, and manufacturing facilities.
Notable
- Corporate address space, not consumer space. An IP here is a Lilly system or a Lilly employee behind the company's network edge.
- Lilly is a legacy holder of an unusually large IPv4 allocation inside the
40.0.0.0/8range, and this AS originates several million addresses out of it. That is far more address space than the company's headcount would suggest, and is a reflection of how the earliest allocations were sized, not of network size today.
Interesting
- Pharmaceutical and industrial firms were among the earliest commercial holders of large IPv4 blocks, having connected in the era when a company could simply ask for a Class A-sized range.
