Static vs. dynamic dhcp assigned addresses

["Mayne, Jim" <j.mayne () TCU EDU>]

TCU has always provided user's with static ip addresses using dhcp reservations. However with the flood of new mobile 
devices it is straining our ability to efficiently assign these types of ip addresses. In discussing a movement to 
dynamic addresses the issue of incident response and troubleshooting comes up.

Would others using dynamic addresses share their tactics and any estimate of added effort involved when tracking down 
issues identified by ip addresses, whether they be from external complaints, IDS logs, firewall logs etc.

Thanks,
Jim
