I have no idea what you mean by "shadow" IP addresses.
Maybe he means a spoofed IP. I haven't played around with TCP/IP in 20 years but back in the day, you could spoof IPs if you have root access on a name server.
I've noticed a large uptick in "tech pedes" saying shit that makes us pedes who actually work in tech quite confused (aka they're blatantly full of shit). Unfortunately, it looks like it makes sense to people who have other areas of expertise.
Also yeah, there's no such thing as a "shadow IP" except in some possibly obscure and limited usage (not a general "hide my IP" kind of way).
Here's a pro tip guys: you can google any actual tech term and get a bazillion results. Try "tail call optimization". Notice how there are literally thousands of results for that concept? Now try "recursive descent parser". Equally obscure, right? But sure enough, you will receive thousands and thousands of results because this is actually a thing. Now try "shadow ip". You may get a result that appears relevant on first glance, but you will quickly start seeing completely irrelevant results, unlike the actual tech terms above. This is how you know that this is not a real term. Real terms absolutely flood the results with relevant results that all say basically the same thing.
NOTE: as I'm sure some of you are thinking, Google is not always reliable for everything, esp. anything political/cultural. But for tech stuff, they are on point. Same general rule goes for Wikipedia.
