General Discussion / Host names for IPV6 address in traffic reporting
« on: May 02, 2024, 06:19:39 pm »
Hi,
When I'm looking at Reporting -> Traffic -> Top Talkers I can see traffic stats per host, for IPV4 hosts I see both hostname and IP address (because DHCPV4 registers leases in DNS or I have just static mappings), but for IPV6 I can see only addresses.
I understand that it is related to the fact that IPV6 devices use SLAAC to generate private addresses even with DHCPV6 in network. So, even with static mappings I cannot use DNS to resolve such temporary IP to name.
To see actual hostname currently I'm opening NDP table to find MAC and then ARP table to match this MAC to IPV4 hostname.
Is it possible to somehow automate this process? Maybe some cron script, which will register SLAAC addresses in unbound dns or just traffic reporting perform this double lookup?
