+# Do not send the system hostname to DHCP servers.

+# Normally NetworkManager includes the hostname in DHCP requests so the
+# server can label leases or register dynamic DNS entries. Most networks
+# do not rely on this, and disabling it slightly reduces information
+# leaked about the device (especially when MAC randomization is used).

+# Individual connections can override this if needed:
