Then next, here what will be given for IPv4 DNS1 and IPv4 DNS2, Internal DNS 1 and Internal DNS 2? Can you tell me here which one we used for our own DNS server and which one used for Public DNS? OR we use both for our or we use both for public DNS?
And also Default Guest CIDR for isolated network what we need to give? and what is the use of this?
And Dedicated, Enable local storage for user instance, Enable local storage for system VMs? need to enable these? and if we enable what happend? and If we not enable what happend?

And this is the most critical part and confusing part for me?
Here, what I do? Like give all the traffics in only one network or need to seperate for each like, Public, Management, Guest and storage?
If i give same network for all the traffics what happend? Give seprate for all the traffics what happend?

And When we click the () tab it will ask for the traffic lable? what is the and it need to given or dont need for this?

Please these because it is very important, here i use all was sepreate, for example, Management vlan9, compute, vlan10, storage (ceph) vlan11, adn storage(ceph) cluster network vlan12 and also use for pub;iuc traffics for seprate Vlans.
