Hunting for MACs and IPs?

Just because IP addresses have become the default identifiers for all equipment on a network, it doesn't mean you don't need other ways to identify. All networking devices still have a unique MAC address-another way of identifying them. The most common format for a MAC address comprises six groups of two hexadecimal digits, like 02:a0:c9:52:49:40 is a MAC address. It can be useful on a network where the machines get IP addresses via a DHCP server. A machine on this network can get different IP addresses at different times. However, its MAC address will always remain the same. So, you can use it for identification. Similarly, most wireless Access Points support MAC address-based filtering, which can control access to the wireless network based on the MAC address. But the MAC addresses are extremely difficult to remember. That's where this tiny utility comes into use. CC Get MAC Address is only 397 KB in size and performs a few limited, yet useful functions. Here we'll take you through them. 

As you can see, there are only a few things you can perform with the utility. Most of the buttons are self-explanatory, so we'll explain only the key ones You get this screen when you click on the 'Retr All' button. Specify the IP address range of all the subnets on your network to quickly retrieve all the MAC addresses  Use Auto-Scan to poll an IP address range for MAC addresses at regular intervals If you know the MAC address of a node and want to find its IP address, enter it all here to find out
