You may want to simply this by using classes. For example, here's a class
"IP_Address":

class IP_Address:
    def __init__(self,ip,hostname,mac_address):
         self.ip=ip
         self.hostname=hostname
         self.mac_address=mac_address

Then:
      new_forward=IP_Address(ip_address,hostname,mac_address)

Then:

      masq_table['forward'].append(new_forward)

then later:

   for ip in masq_table['forward']:
       ...do something here...
