SUMMARY
One can no longer add multiple Public IP ranges, which share the same subnet.
Previously one could take a subnet, and split it into multiple ranges and dedicate them to different accounts.
Now each range must be on a unique subnet.
STEPS TO REPRODUCE
```create vlaniprange zoneId="4549cc45-bc59-421c-bda7-ce097c70de79" vlan=untagged gateway=10.99.0.254 netmask=255.255.255.0 startip=10.99.0.1 endip=10.99.0.100 forsystemvms=false forVirtualNetwork=true
create vlaniprange zoneId="4549cc45-bc59-421c-bda7-ce097c70de79" vlan=untagged gateway=10.99.0.254 netmask=255.255.255.0 startip=10.99.0.101 endip=10.99.0.200 forsystemvms=false forVirtualNetwork=true```
EXPECTED RESULTS
2nd range added without issue
ACTUAL RESULTS
Error message returned:
Error: (HTTP 431, error code 4350) The IP range with tag: vlan://untagged in zone ref-trl-868-k-M7-pangus has overlapped with the subnet. Please specify a different gateway/netmask.
