Summary

Cortland Electronics Corp.

United States · AI-generated

enterprise legacy

CORTLAND is Cortland Electronics Corp., a small network operator in Knoxville, Tennessee that runs under the Milliwave name — the brand appears in its ARIN contact address and in the reverse DNS of its border routers.

What it's used for

  • A small, single-homed network: it announces only a few /24s and reaches the internet through a single upstream, so it functions as a stub rather than as transit for others.

Notable

  • The public footprint is minimal. Most of the address space carries no reverse DNS, and the operator has little presence beyond its registry records, so the specific service it delivers is not publicly documented.
  • Despite the low AS number, treat the size as the real signal here: this is a modest regional network, not a major carrier.
