I'm working on a long-overdue IPv6 rollout here and have gotten to the
point where I've got clients on one VLAN successfully requesting and
receiving leases from a "trivial" single pool and managing a single
reservation. Kea 2.2.0, FreeBSD 13.1
I was surprised that the leases seem to be handed out sequentially. I
had thought that one of the touted advantages of IPv6 is sparse host
density, making net scanning more challenging for rogue actors. Packing
16 hosts into the first 16 addresses of the pool seemed counter enough
to that to have me wonder if I have missed a configuration option somehow.
Sole subnet6 declaration:
"subnet6": [
{
"subnet" : "fd8a:bbbb:cccc:000b::/64",
"interface": "vif2",
"pools": [ { "pool": "fd8a:bbbb:cccc:000b:0::/80" } ],
"option-data": [
],
"reservations": [
{
"hw-address": "11:22:33:aa:bb:cc",
"hostname": "named-host.example.com",
"ip-addresses": [ "fd8a:bbbb:cccc:b:1111:222:3333:444" ]
}
]
}
],
Is there some setting, parameter, or technique to get the lease
assignments from the pool to be broadly distributed?
Thanks!
Jeff
