About this network

An early allocation held by L3Harris Technologies (HARRIS-ATD-AS), originally Harris Corporation's Advanced Technology Department in Melbourne, Florida.

What it's used for

• Corporate networking for a defense and communications technology company.

Notable

• A corporate / defense-contractor network, not a commercial ISP or host.
• The low AS number marks an early-internet allocation, handed out roughly sequentially.

Interesting

• Harris Corporation merged with L3 Technologies in 2019 to form L3Harris; the legacy HARRIS-ATD-AS handle predates that by decades.
