192.0.0.10/32

This single IPv4 address is reserved as an anycast address for Traversal Using Relays around NAT (TURN), which relays traffic when direct connectivity through NAT or firewalls does not work.

IANA marks this address globally reachable for its standards-defined service role. That does not guarantee that a route or TURN service is available from every network.

A system administrator should treat the address as relay-discovery infrastructure, not as an end-user host.

Firewall tip: allow it only where TURN discovery is expected. Otherwise classify it as special infrastructure traffic.
