Is there a way to split an existing into smaller subnets without losing data/comments? i.e. split a /24 subnet into /27 and /28 subnets while retaining existing comments and reservations.
We plan to make it easier but for now you can:
1) export IPs from subnet you are going to split (we suggest csv format)
2) delete original and crete new subnets or change 1st subnet size and create new one
3) import previously exported IPs
4) optionally set resevered for 1st and last IP of each subnet (subnet address and broadcast address)
Thanks
