This hostname is either not configured, or resolves to 127.0.0.2. E-mail servers can query blocklist.example to find out if a specific host connecting to them is in the block list. Many such block lists, either subscription-based or free of cost, are available for use by email administrators and anti-spam software.

Most Linux distributions also incorporate and are configured to use zeroconf. By default, each computer's Avahi daemon will respond to mDNS hostname.local queries, and most shell commands and application program calls that attempt to resolve such names are routed to that daemon by the default hosts: line in the Name Service Switch configuration ...
