From what I can see Quic don't use any upstreams who have a direct connection into Blizzard North America so you are at the mercy of tier 1 providers and any associated capacity problems between them.

They also seem to use Cogent which is terrible... wonder if they bought that bandwidth contract off 2degrees lol

Behodar:

I explicitly asked Blizzard whether 137.221.105.232 was the correct IP address and they didn't respond. In fact, they went further than not responding: they edited my support ticket and redacted the question out.

I eventually managed to get a response out of them, but unfortunately it was "we will not discuss the IP address of any realm".

Any suggestions on where I can go from here? Can we assume that 137.221.105.232 is correct, given that netstat shows it when connected, and it appears to be in the right sort of geographical area?

telemetry-in.battle.net resolves to 137.221.105.232 so not quite I think.

If you want the realm server IP I guess you need to do a packet capture...

Random hail merry but have you tried a VPN? Myself and a couple of guild mates were having issues a year or two ago on (what was then Vodafone). Just to the US wow servers. Random lag spikes for no apparent reason and rest of my network was fine.

Could not figure it out. Tried ExitLag out of pure frustration. Instant fix. Seems there had been some routing issue that the VPN fixed. Used that for about 3 months until the base issue went away. Was the only way the game was remotely playable.

Not saying it is the same issue here, but worth a try? I'm sure you can get a free trial so no real risk involved.

Good spotting. I might have another poke around and see whether I can find another address that looks about right, although I don't like having to do the whole "trial and error" thing!

Edit: Chorus sneaking in while I was typing :)

I haven't tried a VPN although I expect it'll work around the issue successfully, since the problem seems to be between Quic and Blizzard. It was on my "to think about" list, but I hadn't got as far as actually trying one.

I think I've found the right addresses now.

Pings to 64.224.31.40 and 64.224.28.105 are sitting at 290-295 ms, which meshes with what I'm seeing in-game. These addresses are registered to Blizzard.

A traceroute is fine for a while, then hits a "telecomitalia" hop and jumps up after that.

traceroute to 64.224.28.105 (64.224.28.105), 64 hops max, 40 byte packets

The other address does the same sort of thing.

Do other Quic users see the same?

Those addresses help us a heap, thanks @Behodar.

The team will take a look next week for you now that we have some known IPs to work with. 🙂
