We have in the company the scenario that about 50% of the PCs access our Windows Servers (all Active Directory) over 10GBit, the remaining 50% still over 1GBit.
To be able to use the full performance of 10GBit we would like to put these PCs into a separate VLAN which we configure with JUMBO FRAMES.
However, we are unsure how this would affect DNS resolution because of the 2 different subnets.
The Windows servers (AD, Storage, Exchange, ...) would need IPs in both subnets in this case. How does the AD behave here? Would it return both IPs when we query a hostname? Then we would have problems if a 1GBit subnet PC gets the 10GBit subnet IP and vice versa.
Or can we fix this on the corresponding VLANs/subnets which IPs the AD/DNS returns?
I hope you can help me here on the right track.
Thanks a lot, best regards from Tirol
