What it's used for

• The address space is primarily registered to United Telephone Mutual Aid Corporation with netnames like UNITED-190-NETBLK-1 and NET-66-231-120-0-1, indicating a corporate or legacy telecom estate.
• One prefix, 216.196.64.0/21, is registered to Polar Communications with the netname POLARCOMM-BLK-2, suggesting a distinct operational segment or historical acquisition.
