What is the device in the middle?

I did a traceroute on an IP address and got these results. I am only
showing hop 9, 10 and 11, where it crosses over from my provider to their
provider:
9 13 ms 13 ms 16 ms host213-121-193-95.ukcore.bt.net
[213.121.193.95]
10 24 ms 13 ms 12 ms 194.74.65.22
11 18 ms 23 ms 18 ms brhm-bb-1c-ae5-0.network.virginmedia.net
[212.250.15.209]
What is the device in between?
