NAMO - Add / Edit Host - Detail

  • Host Name
    Enter the desired host or domain name in this field. The host name must not be longer than 255 characters and there must not be more than 63 characters between two dots.

  • IP Address

    • Local IP Address
      Activate this option if you want the IP address of your Mac to be automatically assigned to the specified hostname.

    • Individual IP Address
      Activate this option if you want to assign an individual IP address to the host name. You can enter this IP address in the input field(s) below. Which input fields are displayed (IPv4, IPv6, IPv4 & IPv6) depends on the Preferences (Advanced).

    • Reverse DNS lookup
      Select this checkbox if you want to enable Reverse DNS lookup (rDNS) for this host. Reverse DNS lookup (rDNS) is the querying technique of the Domain Name System (DNS) to determine the domain name associated with an IP address – the reverse of the usual “forward” DNS lookup of an IP address from a domain name.

    • TTL (Time to live)
      TTL stands for “Time to live” and it refers to how long a computer or server’s DNS settings are supposed to be cached before they are automatically refreshed.

    • Status

      • Active
        Activate this option if you want the host to be reachable.

      • Inactive
        Activate this option if you want the host to be unreachable. All settings of the host will remain unchanged.
