Python script that takes a list of ips and will perform reverse lookup to resolve hostnames.
Wrote this to audit all our networked devices have correct reverse lookups populated in DNS
--Future--
-Integrate w/ HPNA (pull list of active devices)
-Ping hosts with no reverse records to see if alive
-Check for forward DNS records aswell
-email nicely formatted output on completion so i can make a cron job to run this monthly
##USAGE##
DNS-Audit.py [iplist] [nameserver ip]
iplist should be a file with IPs (1 per line) depends on dnspython package (pip install dnspython)
