Something strange on microsoft servers

[WinFX]

First:
R.I.P Microsoft Zone Online Games (September 14, 2000 - July 31, 2019)

I was bored on my pc, opened a cmd window and ping the old versions of Windows Update, versions 4 and 5 had their own domain while versions 3 and 6 do not have it.
Well I ping the domains "v4.windowsupdate.microsoft.com" and "v5.windowsupdate.microsoft.com" and they sent a response, while also checking to see if it was really still standing in August 2019, I ping it to "v7.windowsupdate.microsoft.com" (never existed).
It is mysterious, since MS is strict with support periods. It has been 8 years since the servers that host these sites are turned off, but the domains after 8 years are still standing.

Maybe there is a way to get updates from the server

Those are redirects to the same (modern?) update website/server, look how they are pinging the same IP address in your screenshot.
