My ISP recently added support for for IPv6 and they gave the following info: Type: 6rd Ipv6 Prefix: 2600:16f0:: IPv6 Prefix Length: 28 IPv4 Border Router: 22.214.171.124 IPv4 Router Mask Length: 0 MTU 1480 IPv6 DNS Server 1: 2600:1621:1::c:1 IPv6 DNS Server 2: 2600:1621:1::c:2 IPv6 DNS Server 3: 2600:1621:1::c:3 Enable Router Advertisement: Enable I'm running Toastman 1.28.0506.3 STD on an Asus N66U. I set up IPv6 as a 6rd Relay with the above details. As far as the connection goes, everything seems to be working just fine. I can get to IPv6 sites and I score a 10/10 on test-ipv6.com. However, I'm trying to figure out how best to configure DNSMasq so that I get hostnames for all the devices on my network when they're using IPv6. Here's the entire DNSMasq config: pid-file=/var/run/dnsmasq.pid domain=home.personaldomain.com resolv-file=/etc/resolv.dnsmasq addn-hosts=/etc/dnsmasq/hosts dhcp-hostsfile=/etc/dnsmasq/dhcp expand-hosts min-port=4096 stop-dns-rebind rebind-localhost-ok interface=br0 dhcp-range=tag:br0,10.0.1.100,10.0.1.200,255.255.255.0,1440m dhcp-lease-max=255 dhcp-authoritative # Stuff below added by text field in DHCP/DNS gui # IPv6 stuff enable-ra dhcp-range=::1, ::FFFF:FFFF, constructor:br*, ra-names, slaac, 12h # Local domain stuff local=/home.personaldomain.com/ cname=home.personaldomain.com,gateway-wan.home.personaldomain.com # Other config stuff strict-order clear-on-reload domain-needed cache-size=8192 log-async=5 I unchecked the following two IPv6 options in the GUI so that I could add my own to the conf file. The reason is that I couldn't see a "slaac" reference in the conf file when they were checked and I wanted to add my own dhcp-range line: - Announce IPv6 on LAN (SLAAC) - Announce IPv6 on LAN (DHCP) My issue is that Tomato doesn't seem to give hostnames to any of the 3 IPv6 address that my Mac gets. If I run a speedtest on http://ipv6-test.com/speedtest/, I can see the hostname for the IPv4 connection in QoS-> View Details, but I only see the IPv6 address for the IPv6 connection. My assumption is that the "ra-names" option that I've set on the dhcp-range is supposed to give hostnames to all the IPv6 address that a computer gets. Otherwise the connection details screens are messy with unreadable info. Also, I also only see IPv4 traffic in IP Traffic -> Transfer Rates. Should I be able to see IPv6 traffic there?
