[2020] Concerns about playing on VPN

With the current happenings in the world, many of us are working from home. I am one of those people and of course I am going to be playing RS while working when I can. My concern is over using my work's VPN on and off when I need to while playing. I understand Runescape's detection systems can be wonky at times. At times I will be switching IP's while logged in (I have to be on different VLANs). Anyone else have examples of them doing this without consequence. Just a little paranoid of losing my account I've worked on for years. I have played several times at work over the past two years, but I am more worried about the switching IPs while logged in.
