What it's used for

• The AS announces 512 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, isolated corporate network rather than a transit or large access provider.

Notable

• Registrants do not fully align with the announcer; while 24.106.3.0/24 is registered to JEWELERS MUTUAL INSURANCE, the second prefix 64.215.7.0/24 is registered to Level 3 Parent, LLC under the netname LVLT-ORG-64-212.
• The address inventory is minimal, consisting of two /24 blocks, one of which appears to be leased or inherited from a former ISP (Level 3).
