iRules IP Comparison Considerations with IP::addr Command

Hope so.

Just a few notes on performance;

• When using the IP::addr command to compare IP addresses with the if command, always use prefix notation for subnet masks (/24 for instance) rather than the mask x.x.x.x syntax as this uses less CPU cycles

   

• When using the IP::addr command to compare IP addresses, specify any subnet masks with the second address or subnet to be compared, not the first; doing so uses less CPU cycles
