There are three possibilities, in my opinion. 1: Microsoft is using these servers, so they have a new public IP address and a new IP address range. (Everything needs to be redone on the geofilter side.) 2: Microsoft is still using AWS as a "hybrid backend" for some servers. In this case, some AWS IP addresses would remain valid (no total change). 3: If Microsoft uses "BYOIP" (Bring Your Own IP), this is a feature where a company brings its own IP addresses to the cloud (AWS, Azure, or other). In this case: The IP addresses belong to Activision/Microsoft, not the cloud provider. They can be used on both AWS and Azure. (Result: the player would see "the same IP addresses," even if technically the infrastructure has changed providers). PS: I'm not an expert but I think that Microsoft will use its ecosystem which in the long term is much more profitable but from memory I don't think that Azure is better established than AWS (e.g. South America) for Gaming. So we'll see.

No need to leak, it seemed obvious. Call of Duty = Microsoft Azure = Microsoft

On Windows, there isn't much you can do about the network. You can tag your applications with DSCP tags if your router supports packet prioritization using DSCP. Some people optimize their Windows using the registry. Google is your friend, but if you want, you can test software. Windows: Resource Monitor (resmon.exe) allows you to see which processes are consuming bandwidth. Third-party tools like NetLimiter or cFosSpeed allow you to limit or prioritize certain applications. Router: All routers these days, or 99% of them, have QOS. QoS → its main role is packet classification and prioritization (e.g., gaming > voice > download). Bandwidth control → is achieved through mechanisms such as HTB (Hierarchical Token Bucket), HFSC, or FQ_Codel/SQM, which manage efficient throughput distribution. To be more technically precise: QoS ≠ direct throughput management → it's a "who comes before whom" logic in the queue. HTB or equivalents → allow hierarchical classes to be defined with minimum and maximum bandwidth allocations (per user, per IP, per protocol). In modern routers (e.g., OpenWrt), the two are often combined: Classification (QoS) → to identify sensitive flows. Scheduling/Shaping (HTB, FQ_Codel, CAKE) → to efficiently allocate and limit bandwidth. So, to put it simply: QoS = packet priority. HTB/HFSC = bandwidth control = actual bandwidth allocation. For gaming, both are very important, especially if you're playing on a PC. Having a 240 Hz monitor isn't enough. Optimizing Windows is important to avoid input lag in games. And when it comes to networking, there's no magic formula: a very good ISP connection and a good router to prioritize game packets and other... In your case, that's gaming, especially Call of Duty. This means you need to make sure your game takes priority over other tasks. No packet loss, no buffering, and no excessive ping; your game remains the top priority, even when downloads are overloading your bandwidth.

On these beautiful words, take care of yourself and have a good evening.

About the network card improving sound: we’re not talking about audio frequency or equalizers. None of that! Honestly, it shouldn’t even need explaining; anyone familiar with networking should know this. 2- I understood, don't worry, and I am very familiar with the network because I am currently a sysadmin. What I’m talking about is data packets transmitted from the server to your client. A network card that handles these packets and queues better ensures that the data arrives without delay. These packets carry critical info, like enemy footsteps and shot registration. With an efficient NIC, they don’t get delayed or ignored. 3 - In short, packet and delay management is actually shared at several levels: The Network Interface Card (NIC) It handles the reception and transmission of packets at the hardware level. It manages the queues of incoming/outgoing packets and applies certain optimizations (such as offloading, interrupt moderation, or buffering). A high-end network card can process packets faster, reduce latency, and prevent losses if the bandwidth is high. The Operating System (kernel network stack) The kernel (Windows, Linux, etc.) manages scheduling, buffering, and the transmission of packets at the software level. It’s the one that delivers packets to applications (your game, for example). The Network Protocol (TCP/UDP, etc.) UDP (often used for games) sends packets without delivery verification → faster but with a risk of packet loss. TCP guarantees delivery (retransmission, ordering), but adds latency. The Quality of the Network (routers, ISP, the Internet in general) Even with a good network card, if your connection is unstable, saturated, or poorly routed, you will experience latency or packet loss. If necessary, I can give you a course on how the network works from layer 1 to 7.

@Krush parce que quelqu'un a dit. Non pour être plus sérieux mon but est de dire aux personnes d'arrêter de vendre du rêve et bien souvent sans fondement. Ces matériel pour la plus part coûte cher et difficile a configuré et pas adapter a toutes les personnes donc sans le vouloir influencer l'achat de ces matos qui pour 90% des gens ne servent a rien et certainement pas pour du gaming.

At home I changed the color of my LED to red and I went from 2 to 4 K/D.

Okay, let's admit that what you say is "true." Explain to us why it's better. Why an Intel card and not Marvel, for example? Why SFP? SFP+ RJ45/FIBER. Which L2/L3 switch should you choose and why does it improve your network? Why do you get better sound when you change your network card? What is bridge mode and why should you enable it? And if you don't have one, what should you do?

Bullpoopy don't listen to this advice, you'll waste money for nothing... Do you even know what QOS is? 1: Prioritize traffic 2: Distribute bandwidth fairly 3: Guarantee performance levels 4: Ensure reliability for critical services You only have one PC with an internet connection, a QOS won't do you much good.

To answer the DM, I don't use cake, but fq_codel for my own reasons, being on a local network with four servers and various network devices. A well-configured fq_codel handles all of this for me perfectly. For prioritization, I switched to hfsc, which isn't the best, but it gives me flexibility when I decide to play my FPS games, even if my network is overloaded. It's not the best QoS I've set up, but since I don't play much anymore, or even at all, this is a good alternative.

Thanks to @Chaiyoabc for all the explanations and for pointing us in the right direction. I think I've found the right PMU.

I installed OpenWRT and SQM after hours of figuring it out and battling with myself. I finally managed to get everything set up. They even suggested I do a bufferbloat test. "See screenshot," and after several tests on my favorite video game, COD, the result is amazing. I didn't know he had created such a well-thought-out geofilter.

Cake , Fq_Codel , Sqm , Pmu i don't speak chinese

Okay, but there are restrictions depending on the routers you use, right? My home has a 2GB download/upload speed. Which router do you recommend? And how do I configure the MPU? That's something I really want to do because @Chaiyoabc managed to do it, so I'd like to succeed too.

Ah, okay, interesting, but how come it only works with OpenWRT? I can install Cake's QOS on a system other than OpenWRT because I'm tired of being run over on COD. So I absolutely need a Flint 2 to play COD properly. And one last thing I was able to read on Google Dumaos is a layer applied on openwrt, but how come it doesn't have the same result qos as Openwrt?? I really don't understand anything about all that....Pffff.
