"broadcast" => "192.168.7.255",
"dns" => "192.168.7.1",
"domain" => "hunleth.lan",
"hostname" => "nerves-9780",
"interface" => "eth0",
"ip" => "192.168.7.190",
"lease" => "86400",
"mask" => "24",
"opt53" => "05",
"opt58" => "0000a8c0",
"opt59" => "00012750",
"router" => "192.168.7.1",
"serverid" => "192.168.7.1",
