512k day bug

This is not a problem I have, but a topic of hardware and software limitations. It seems we passed a milestone of 512k ways of getting somewhere on the Internet. Something about address space allocating 24 bits to makeup source and destination addresses. I know some of MG's seniors have IT and networking experience, so tell us, is it going to get harder to get to sites where/when routers have these problems. My figuring is 19 bits gets to 512k, so the other 6 bits to get to 24 must be what? Control bits or zone bits or something? Enlighten us. I see 3000 people here at a time so thats info going and coming to/from a lot of places at one time. I've seen reports of some cloud services having connection problems. What's up? And Thanks!

 

Some older equipment has 512k entry limit for address routing, that's all.

Its as simple as upgrading ancient equipment.
