@Dashrender said in IPv6 Subnet Masks - CompTIA Network+ N10-007 Prof. Messer:

It's absolutely true that IPv6 gives us billions and billions of small networks worth of IPs(each of those smalls being likely larger than the full IPv4)

Right, both are just a flexible pool. One is just way, way bigger.

@scottalanmiller exactly what I was looking for!

This is a rental home, so don't want to run cable throughout the house to connect the switch to the router. Resolved the issue by putting in a couple of powerline ethernet adapters.

Glad I could help JB in keeping his blood pressure in check. 😉

By default, traffic will pass between VLANs 1 & 2, unless you go into the firewall & add rules to deny traffic

One wrinkle you should be aware of (this needs to be fixed in our web UI!) -- if you change the ZT-managed range from /24 to /23 or /22 you will also need to change it on all the devices. We should add a feature to renumber automatically since right now it's tedious.

Correct, you would want to change your servers first. so that devices in the new range can get answers back.

In my case, printers are always DHCP reservations. So as soon as I update the DHCP scope that will come down.

I've seen you post that before - I think I need to adapt that.

Everything is DHCP reservations except the core server infrastructure, HOST, DC, DHCP, and the Router. Exverything else is DHCP reservations, Printers, secondary servers, PBX, everything. Desktops and phones, just normal DHCP.
