Inconsistent packet loss during instances (Dungeons/Eureka)

Situation:

I have recently moved, and I have currently been experiencing packet loss or some other form of lag while playing FFXIV. I only notice it in dungeons as I play primarily tanks, and I have noticed that there will be "rubber-banding" with mobs, and damage received by AOEs when there are no indicators even on screen (eureka while reflect farming).

Some relevant information:
- Data Center: Primal
- Home world: Hyperion
- ISP: Comcast (connection is stable at ~170mbs down and ~12mbs up)
- State: Georgia
- Connection: Wired into modem via Ethernet
- FFXIV ping: Normally ~80ms

Today I did as much testing as I could to figure out if the issue was on my end, or if the issue was "down the line" as I have not had any problems playing other games.

The first thing I did was disable all firewalls in order to insure that that wasn't an issue, it was not.

I updated my router and modem firmware and reset them both. Not the problem.

I changed Ethernet ports on my router. Not the problem.

I then started to check things that I might not be able to change, such as running an "tracert -d" through cmd, using the IP address 204.2.229.98 as that was the IP address that I found through resource manager, as that was the IP address that FFXIV was connecting to. I ran this multiple times and I only had 2 hops drop any data, 204.2.229.234 and 204.2.229.98 which were always the last two IP addresses in the connection chain (link 17 and 18). After looking up the IP addresses online, they seem to be hosted by NTT America, which when looking up NTT America in relation to FFXIV there seems to be a history of issues with the data center and the game.


Now I am not 100% certain that that is the correct endpoint IP address to check, but that is the best that I have to go on. Does anyone have a Suggestion to fix the issue? Or a way (preferably not involving a VPN) to try and connect to the games servers without using those specific IP addresses, as they seem to be the issue?

And and all help would be appreciated,

Everyone I know with a comcast connection on the east coast is experiencing the same thing. Unless you have a way of contacting the network administration for that particular router, there's nothing you can do on your end aside from use a VPN and pray for a different routing table to avoid the bad hop.

At least this is what my introductory knowledge of networking tells me.
