Was able to ping an address outside of my subnet

So I was looking at Wireshark trying to analyze the mess and learn the tool. I saw something wierd in where hundreds of TCP packets were being sent to an IP address.

My network is let's say 192.168.254.0/24

I was watching packets going from 192.168.255.1 to 192.168.255.2.

The Mac address belongs to my router, so my router was sending packets to 192.168.255.2.

Is 192.168.255.2 me? I could ping 192.168.255.1 but not .2.

How could I send pings outside of my subet and what could my router be doing that it would be sending packets over a different subnet and for so long?

It's just a mutlipurpose wifi/switch/router from Arris
