I'm not sure why you would say it's a 'myth' that dedicated servers prevent DoSing: the dedicated servers themselves might come under DDoS attack but dedicated servers also have anti-DDoS protections in place, unlike the end user who has zero protection (except for whatever measly anti-DDoS protections your modem/router might come with). And modern cloud gaming servers are definitely more resilient than the average home broadband connection or consumer ISP. Peer-to-peer will always expose people's IP addresses, and I don't know of a method current available that would allow for the masking/encryption of people's IP addresses while using peer-to-peer connections, except via client-side VPN. But definitely, if you have a better solution than the current one that exposes people's IP addresses, Bungie needs to hire you because as it stands, Bungie's 'hybrid peer-to-peer' leaves people vulnerable to network manipulation including lagswitching, drophacking, and DDoSing, none of which is possible without Bungie's terrible decision to run the game on p2p. [quote] [b]"The privacy flaw A fundamental flaw of any peer-to-peer network model is that it reveals your IP address to every player you meet in PvE or PvP. When we have a look at the connections Destiny 2 established in one of my 4v4 Crucible matches, we can see three Bungie servers located in the USA, one Limelight Server located in the UK, one Blizzard Server located in the UK and the other seven players located in France, Germany and Turkey. Peer-to-peer IPs By revealing the IP address of these players, the game makes it very easy to find out the country and city/town where they live. So, I can then block or throttle the traffic between my client and theirs, or I could launch a DDOS attack to affect their online experience—something streamers have to deal with on a regular basis, and has resulted in persistent problems with the relatively high stakes PvP mode Trials of the Nine. Bungie issued a swathe of two-week bans to DDOSers recently, but the attacks keep coming. Security and hacking "Never trust the client" is a saying you'll hear often from developers who work on multiplayer games. When you let the client take care of sensitive tasks like hit registration, then this makes it a lot harder to protect your game from hacks. Bungie faces this problem with the peer-to-peer network model in Destiny 2. To shield the game from hacks on PC, Bungie is preventing applications from injecting code into the game. The downside of this measure is that this also blocks any and all applications that provide an in-game overlay like MSI Afterburner, RTSS or Discord. It also blocks apps used for streaming or gameplay recording like DxTory, and OBS when you try to use the game capture mode. Despite these efforts, which harm legitimate players, hacks still exist for Destiny 2."[/b] [/quote] https://www.pcgamer.com/the-strange-science-of-destiny-2s-uniquely-complicated-netcode/ [quote]We need to stop the myth of dedicated servers preventing DoSing - without change it would just result in a host and everyone would get booted instead. A more realistic approach is simply, while not ideal for a competitive setting, keep the Bungie accredited P2P network structure but up the encryption level currently at place. While it could introduce lag, I know there are measures to prevent static real IPs from being grabbed. This is all besides the point - but a VPN should never be required to play a game.[/quote]
