ndisc6 -1 fe80::1234 eth0 Replace eth0 with the correct interface name, of course.

No, DreamHost is not giving you 2 IPv4 address just for fun. Notice their Unique IP is a separate option with a cost. You are sharing non-unique IPs, possibly with thousands of other sites. They can't possibly host a million web sites on a hundred thousand IPs unless some shared. Even that is relatively rich because they were an early adopter. A new hosting ...

I found a couple of ways to do this, but they're both a bit ugly. First, you can use dns-sd -q and specify the ptr record type... but you need to convert the address you want to look up into nibble-by-nibble reverse format by yourself. For example, to look up fe80::4e6:97e7:d892:d977 you'd use: dns-sd -q 7.7.9.d.2.9.8.d.7.e.7.9.6.e.4.0.0.0.0.0.0.0.0.0.0.0.0....

Due to your requirement for this to be reflected in the kernel's neighbors, and your reluctance to install software, try ICMP echo: ping -c 1 fe80::1234%eth0 Does not really matter what protocol you attempt, so long as it is IP based. If you are willing to install software, nmap has discovery features. Here is a NDP only scan, output to a XML file (and ...

There is nothing wrong with that. Since your website resolves to both IPv4 and IPv6 addresses, the browser (or whatever HTTP client) at the other end may pick an address in random order, or prefer IPv6 over IPv4 (or the other way round). It may very well connect over IPv4 sometimes, and IPv6 at other times. The behavior has to be browser-specific and ...

I'm assuming that you are using these three packages to provide the options in use: ifupdown, bridge-utils, vlan. The two later provide the commands brctl and vconfig, both obsolete, but more importantly they provide Debian-specific plugin scripts to ifupdown. While brctl is still used in these scripts, vconfig is not even used (and replaced by modern ip ...

The default route of the one active interface is used. I guess your phone has 2 sim slots usually an inactive interface unless your VPN is up. "2:0:0:0:0:0" is a HOST over the "enc" interface, tunnel or vpn The interesting parts are "2409:8800:" a tunnel to somewhere in "China Telecom", hopefully inactive.

I think in your case you can use Dynamic prefix forwarding, my example of rule in /etc/config/firewall: config rule option name 'HTTP-SSH-IPv6-myserver01' option src 'wan' option proto 'tcp' option dest 'lan' option dest_ip '::2c18:81a2:3422:f690/-64' option dest_port '22 80 443' option family 'ipv6' option target 'ACCEPT' ...
