IP address 192.168.1.255 active every 30 seconds - why?

The IP address 192.168.1.255 is active every 30 seconds - why? I use Virus Barrier and also Little Snitch to monitor network receiving and sending activity... Since I began this process I've been baffled by the fact that this particular IP address, 192.168.1.255, is so active - about every 30 seconds the Little Snitch window shows sending and receiving activity after the the line "cupsd." I assume it's harmless - but since I can't seem to determine why this is happening, I can't be 100% sure... I hoping someone familiar with this network issue can explain why this is happening. Thanks very much.

Hi there,

An IP address starting with 192.168 always is associated with a router. To have items being sent to and from it is therefore normal.

Nothing to worry about.

cupsd is a UNIX printer utility. Do you have a networked printer?

I do have a Canon MG5220 printer that I print to wirelessly with my macbook pro... but it's hardly ever powered on. As long as this ping or whatever it is, is strictly local (internal) and not a nearby address, like in the neighborhood, I guess I can relax. Security for macs is not as secure as it used to be. Thanks for your help! Much appreciated. & Happy Holidays!
