When a network is mostly assigned using RFC 1918, DNS resolution is not useful
and devices are displayed by IP address.
When $config['force_ip_to_sysname'] is enabled, use ip_to_sysname() to display
the device hostname or SNMP sysName if present instead of the device IP address.
UI modified by this patch:
- Hover in Dashboard Availability Map (/overview)
- Name in Availability Map (/availability-map/)
- Title of device page (/device/device=...)
