We're on 24.04 and this is still the case.
There is absolutely no reason to be asked about subnet.
IPv4 CIDR segmentation is pretty cut and dry
For any given IP address in CIDR format, the "Network" will always be the same, no matter the environment.
For example:
# ipcalc 172.16.59.32/27
Address: 172.16.59.32 10101100.00010000.00111011.001 00000 Netmask: 255.255.255.224 = 27 11111111.11111111.11111111.111 00000 Wildcard: 0.0.0.31 00000000.00000000.00000000.000 11111 => Network: 172.16.59.32/27 10101100.00010000.00111011.001 00000 HostMin: 172.16.59.33 10101100.00010000.00111011.001 00001 HostMax: 172.16.59.62 10101100.00010000.00111011.001 11110 Broadcast: 172.16.59.63 10101100.00010000.00111011.001 11111 Hosts/Net: 30 Class B, Private Internet
There is absolutely no possible scenario for this .32/27's subnet to ever be anything other than "172.16.59.32".
