NOTES

• Requires port 443 to be open on the BlueCat DNS/DHCP Server firewall in order to communicate with the BlueCat Address Manager API via HTTPS
• Should NOT require any pip installation of python libraries, python3 native libraries only
• Tested provisionally against Integrity 9.3 only, should function on Integrity 9.1+
• Expected to be called periodically to update the Address Manager, only supports default DATETIME format and does NOT scan/decompress .gz syslog files only the current one
