Router Logs and Plex

I replaced my router with a Netgear Nighthawk that retains connection logs. Using Plex works fine as does remote access.
In reviewing the recent log activity, I see these types of examples:

All of these connections get port forwarded to my Plex server (the xx:xxxxx in the url),

Performing a reverse IP lookup show some in Dallas (my area), but the 54.154.200.193 is shown in Ireland. Is this a Plex (the company) service located in Ireland (ISP is shown as Amazon)? I’ve not noticed any unusual activity on my Plex server, but then I’m not looking at the activity all the time. I wasn’t accessing my Plex server at these times, but suppose the Plex server could have had some activity that wasn’t directly related to users.

Any clues/comments?

Yes, A portion of Plex exists in the Amazon cloud. Those IPs are what you’re seeing. just do a nslookup 54.154.200.193 and you’ll see

Thank you. I knew that with all of this type activity being forwarded to my Plex port, it was likely not my local Plex server but something to do with Plex itself. The Ireland bit was unexpected.

Non-authoritative answer:
193.200.154.54.in-addr.arpa name = ec2-54-154-200-193.eu-west-1.compute.amazonaws.com.

Some of Amazon’s servers are in Ireland.

Aren’t cloud-based services great? (har har)
