No way, it’s 2 subnets, 1022 hosts!

Definitely 4 subnets, but I thought it was 510 hosts too.

Wait, how can there be 2048 hosts with a /23? That seems off.

I think it's actually 4 subnets, 512 hosts.

4 subnets, 510 hosts sounds right!

I’m a bit confused. I thought a /23 mask would give us 1022 hosts, but now I’m wondering if that’s for a /22 instead.

I practiced a similar question last week, and I think we get 4 subnets with a /23 mask. But I can't recall the exact number of hosts per subnet.

I remember something about the formula for hosts being 2^n - 2. So if we have 23 bits for the subnet, that might give us 512 hosts, but I’m not sure about the subnets.

I think we need to calculate the number of subnets first. If we start with a /21 and go to /23, that’s a 2-bit increase, right?

I'm pretty sure the answer is to add the _collab-edge SRV record to the branch DNS server. That should resolve the issue.

Hmm, I'm not too familiar with Huawei's desktop cloud components. I'll have to read through the options carefully.
