Bug Type: Feature/Change Request
Bug description:gethostbyaddr time limit
Description:
------------
When using gethostbyaddr with an IP it will return a host name just what we
want. However, if there is no host name to return it stalls and takes 20-30
seconds PER IP lookup. If it CAN return a host name it does so in <1
second.
Example - I can loop through 5 IPs that resolve to hostnames in .7 seconds.
This includes database calls, and updates.
Example 2 - I can loop through 5 IPs that DO NOT resolve to hostnames in 3
minutes!!!
This needs to be fixed, or a second parameter option for max look-up time
per-ip.
gethostbyaddr(IP,Max_Execution_Time) as example.
