There is talk on the news about IPv4 addresses nearly reaching their maximum on the Internet. Will this affect companies using IPv4 and what impact will this have on Network Qual?

I don’t think running out of IPv4 addresses will affect people, at least not in the short term. Most equipment and software I see these days is compatible with both IPv4 and IPv6 - you’ll be fine.

Regarding Network Qual - you have to record your critical IP addresses somewhere and somehow just in the same way as you do (or should) already for IPv4.

I haven’t moved to IPv6 yet because I have an uncanny ability to remember lists of IPv4 IP addresses and various subnetworks. With IPv6 this ease of remembering doesn’t seem feasible.

I hope this helps!
