This would mean associating the hardware with the IP address. &nbsp;Unless you have some traffic or some other log that has the hardware's MAC address, you would not be sure it hasn't changed hosts. &nbsp;And even then, the MAC can change if they swap out the network card. &nbsp;

Dating a MAC address would work great also.<br />
The NIC/MAC have not changed in the machine in question.<br />
<br />
Is there a way to do this withing the server or shoud lI talk to my network admins to pull timed logs?<br />

You can see if the server logs (or any application logs) have the MAC/NIC info in them, but you will probably need to talk to the network admins to see if they have the info.

Does DHCP or DNS keep an Archival log anywhere?

Nothing persistent in either case. You'd have to make things up to track it.<br />

Is there a way to determine the length of time a computer/hostname has had the same IP address? I am looking at a year or more of timing data.<br />

Time a host name has had an IP.

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

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).

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.
