                     45: is a easy-to-use proxy ARP daemon.
                     46: It watches ARP request packets visible on the interface specified by argument
                     47: .Ar if_name ,
                     48: and sends proxy ARP reply to the sender if the ARP request queries the
                     49: MAC address
                     50: .Pq ethernet hardware address

                     54: .Ar mac_addr
                     55: is th MAC address to be published for the specified hosts.
                     56: It is normally the address of
                     57: .Ar if_name .
                     58: The format of
                     59: .Ar mac_addr
                     60: must be 6 colon-separated bytes of hexadecimal value, such as
                     61: .Ad 00:00:01:01:14:46 .
                     62: The keyword
                     63: .Ad auto
                     64: can also be used to use the address of
                     65: .Ar if_name
                     66: from the system configuration

                     68: .Ar net_addr
                     69: must be in dotted quad notation
                     70: .Pq for example Ad 133.138.1.134
                     71: or be a 32 bit hexadecimal value starting with

                     74: .Ar net_mask
                     75: can likewise be speficied as a dotted quad or hexadecimal value,
                     76: or alternatively as a mask length. The following address specifications
                     77: are therefore equivalent:
