+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.
