You can save your own variables in the leases file for non-static leases:
on commit {
if static {
# set is-static = " --> STATIC";
} else {
set is-static = "";
set my_duid = option dhcp6.client-id;
set my_duid_hex = pick-first-value(binary-to-ascii(16, 8, ":", option dhcp6.client-id), "");
set my_given_hostname = option fqdn.hostname;
}
}
Lease:
ia-na "mbl\022\000\001\000\001\025Yy\267lbm\207\267\370" {
cltt 0 2020/07/12 12:45:07;
iaaddr 2001:xxxx:yyyy:40:50f7::ee {
binding state active;
preferred-life 9000;
max-life 14400;
ends 0 2020/07/12 16:45:07;
set ddns-rev-name = "<redacted>";
set ddns-dhcid =
"\000\002\001\320F0\342\231\334\262\211\351u\023\260\207\200\240%\230\004ZD\035\370\221f\367E\225\245e\234\2154";
set ddns-fwd-name = "Karen-PC.example.com";
set my_MAC = "6c:62:6d:87:b7:f8";
set my_given_hostname = "Karen-PC";
set my_duid_hex = "0:1:0:1:15:59:79:b7:6c:62:6d:87:b7:f8";
set my_duid = "\000\001\000\001\025Yy\267lbm\207\267\370";
set member_of = "Microsoft";
set pool_type = "Microsoft";
}
}
Hope this helps,
Bill
