I'm trying to figure out how this could have happened, but I control so few IP addresses that many of my DNS entries are manually assigned. And you'd have to be incompetent if you have access to set DNS records and you set them to RFC 1918 addresses. Anyone have any theories on how this could happen?

I imagine it has something to do with how MS creates bypasses for host files for systems xpsp2 onwards ... by [1] it suggests Win10 still does.

Through a series of connections I know a guy that knows a guy that works at Microsoft that was made aware and the changes have been reverted. Give 'er 30 minutes TTL ;)

It's an IP address reserved for private networks:

I don’t know man, putting microsoft.com on your router sounds like a massive reduction in latency. Congrats on the achievement.

What could a TLA do with this if it had time to plan ahead?
