 Set the forward and reverse DNS entries for a host with DNS services provided by Constellix. Supports IPv6 and IPv4.
 
+## Super Super Important

+As you will see below - this is a slow, very painful process. Constellix's API sucks. If you can use any other DNS hosting service - do it - don't waste your time here. If you are stuck with constellix (like we are) and you find this script useful - great. Please contact constellix and ask them to take their API seriously.

 This is a slow process.
 Constellix doesn't have any way to find a domain record with a simple search, so we have to look for parts of the domain until we find a match - for IPv6 records - this takes a lot of API requests.
 Further hindering the process is authentication errors with Constellix's API. Over 50% of valid API requests fail against the API with a `401` error. Once Constellix fix this - it will double the speed of these updates.
+Constellix's API now take 20+ seconds to respond to most requests. Expect updating the forward and reverse records for one domain to take well in excess of 5½ minutes (sometimes up to 20).
