I've created like 20 total accounts from my home IP over the last 2-3 years. I'm actively using ~10.
I've never experienced any issues.
However, I have only one account automatically follow & unfollow (pretty safe settings too).
I guess if you plan to do shady stuff with those accounts, creating 20 over your home IP is a bad idea. In the end it's simple: The less accounts you have per IP, the less accounts will be banned if one account gets flagged.
