What it's used for

• The AS announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.

Notable

• Registrants are mixed: 205.201.61.0/24 is registered to ISC Constructors, LLC, while 184.180.8.0/24 is registered to Cox Communications Inc., suggesting a leased or historically allocated block.
• The inventory consists of two distinct IPv4 /24 blocks and a single IPv6 /48, reflecting a modest footprint typical of a large industrial enterprise managing its own internal connectivity.
