Answer the following questions to describe your code submission. Please keep
all lines to a maximum of 80 characters wide.

1 - Explain how you convert the IP address 1.2.3.4 into the correct format for
    a PTR request.

    We reversed the IP address to 4.3.2.1 by tokenizing at the periods and
    then putting them back in correct order. Then concatenated the string portion on to the end of that
    in-addr.arpa. , to give 4.3.2.1.in-addr.arpa.


2 - Explain the fields of an SOA record. Which of these would be interpreted as
    an email address and how so?

    There are 7 different fields: 
    MNAME (The primary master name),
    RNAME (The email address),
    SERIAL (The version number of the zone data),
    REFRESH (How often secondary servers check for updates),
    RETRY (How long to wait before retrying after a failed refresh),
    EXPIRE (How long secondary servers keep data if updates fail),
    MINIMUM (Default TTL for negative responses).

    The RNAME would be interpreted as the email address and you would replace 
    the first . with an @ to turn into the normal email address structure.
