Lease times can &quot;wrap around&quot; in the U-fix 32-bit environment. &nbsp;If something like a &quot;budget&quot; router with an embedded linux kernel issues leases and it sets the expiration date beyond 18 January 2038, the time can wrap around to 13 December 1901. &nbsp;If you see &quot;funny looking&quot; lease expiration dates keep this in mind.

Lease times can "wrap around" in the U-fix 32-bit environment.  If something like a "budget" router with an embedded linux kernel issues leases and it sets the expiration date beyond 18 January 2038, the time can wrap around to 13 December 1901.  If you see "funny looking" lease expiration dates keep this in mind.

There has recently been an unnecessary amount of IP acquisitions on our DHCP server and I need to discover which ones have been leased today. &nbsp;How do I get this info from DHCP server, I have never quite understood why it only shows expiration (not acquisition time/date).<br />
<br />
Thanks

How do I discover DHCP's latest entries?

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
