In the DHCPv6 server, is it possible to reserve an IP address by
interface-id(18)? I tried what I thought might work:
{
"Dhcp6": {
"reservations": [
{
"interface-id": "Gi0/0/1.240",
"ip-addresses": [
"2001:0:2:8::abcd"
]
}
]
}
}

In Kea DHCPv6, I noticed that option 18 "interface-id" is not stored in the
lease6 table in mysql. There isn't a column for it. Is it possible to include
option 18 in the "logging" options if it isn't to be stored with the leases?
With debug on I can see it is received:
relay[0]: msg-type=12
"client-class": "iid1"
},
{
"pool":
"2001:0:2:e::667-2001:0:2:e:7fff:::fffe"
}
],

What I don't understand is why you didn't just use a straight UTC timestamp in
an int or bigint field. You can add said timestamp right in your sql query as
unix_timestamp(now()) which will produce an EPOCH time in the column. If you
need to see it as an actual date/time for some reason, you w
Perhaps you could set the desired options within the class instead of in the
subnet specification? You could have a class for PXEClient and a class for
everyone else? I'm not sure the below is correct but maybe on the right track?

"client-classes": [
{
"name
I assume what OP is talking about is the same behavior from ISC DHCP where
"fixed-address" did not store a lease so any device that matched the conditions
could get the IP.

Is it not possible to, instead, check the conf file on host2 where it will live?

Yes. You can do it just like this in the subnet section (this is for DHCPv6
but i imagine v4 is similar):
"subnet6": [
{
"valid-lifetime": 600,
"preferred-lifetime": 540,
"subnet": "2001:0
I believe:
select hex(hwaddr) from lease4;
will get you an ASCII mac address. Someone correct me if I'm wrong.

Assuming your configuration is correct, it could be that the substring is wrong

Preferred lifetime needs to be somewhat lower than valid lifetime:
"valid-lifetime": 86400,
"preferred-lifetime": 79200,

You can use substring to do that. Here is an example of it in use:
match if substring (option dhcp-client-identifier, 1, 3) = "RAS";

I think he was asking what happens if the servers can't see each other and both

This may be beyond the scope of what you were asking, but you can store some or
all of the config in MySQL/MariaDB:
https://kb.isc.org/docs/using-the-kea-configuration-backend which may make
