Subject Re: Add subnet to public networrk

You need to change 2 tables:

update cloud.vlan where id=1 (assuming this is your public IP range) set
ip4_range="a.b.c.d-x.y.z.w" (here use your brain and see if you need to
change both start and end IP or just one of those two - depending on in
which direction you are expanding. THIS ASSUMES that you are just extending
the existing IP range with additional consecutive IPs. In case you are
adding a range that is NOT consecutive to the existing IPs - then another
approach might be needed (not shown here, have idea of how to do it, have
not tested it - but I can reply with a separate email if needed)

Now, also add records in the user_ip_address by possibly cloning existing
record of a sample (unallocated !) public IP - but changing id, uuid,
public_ip_address. mac_address values - make sure all those values are NOT
duplicated and use logic/brain on which values to put in - i.e. the next
value after the biggest existing value for the mac_address and id, while
public_ip_address and uuid just need to be unique.

mgmt server restart is not needed.
(backup you DB before any actions please).

This should work fine (tested it briefly myself)
