I have a DHCP server running on RHEL 6.6. I understand the process (somewhat) involving how the conversation goes from a protocol standpoint to set up a lease. 1 - The DHCPDISCOVER message. 2- The DHCPOFFER, 3- the DHCPREQUEST, and 4- The DHCPACK. However what does it mean when you see the following activity in a log? Notice how there is continued activity on the IP long after the initial DHCPOFFER took place. What is going on here? Is this just the client renewing/requesting the same IP therefore no DHCPDISCOVER OR DHCPOFFER needs to take place?

Yes, a request for extension of the lease don't need the DISCOVER/OFFER part.
