Apr 21, 2020 · IPv6 is designed to solve many of the problems of the current version of the Internet Protocol suite (known as IPv4) with regard to address depletion, security, auto-configuration, extensibility, and so on. IPv6 expands the capabilities of the Internet to enable new kinds of applications, including peer-to-peer and mobile applications.
Aug 27, 2012 · Use both IPv4 and IPv6. You should use both IPv4 and IPv6 addresses. Nearly everyone on the Internet currently has an IPv4 address, or is behind a NAT of some kind, and can access IPv4 resources.

In order for your IPv6- only network to be able to reach IPv4 addresses, a gateway is required, which has access to IPv4. This is generally done with a NAT64/DNS64 gateway, which translates IPv4 addresses into "fake" IPv6 addresses, and accepts connections to those "fake" IPv6 addresses and translates the connections to the IPv4 network.
Oct 20, 2014 · As Michael mentioned, starting with Nginx 1.3.4, the ipv6only parameter defaults to on. Therefore, if you want to host multiple domains on both IPv4 and IPv6 with a single Nginx server, you are forced to use two listen directives for each domain server block: listen 80; listen [::]:80;
Officially, ::ffff:x.x.x.x is the format for an IPv6-mapped IPv4 address - there are of course also a number of transition mechanisms, namely 6to4 and its relative, 6rd, which map an IPv4 address into a global IPv6 one for the purposes of providing IPv6 access over IPv4 by creating an IPv6 prefix that is derived from the IPv4 address it's carried over.
Nov 2, 2012 · 30. :: is the IPv6 "unspecified" address, equivalent to 0.0.0.0 - the [] is notation to separate the address from the port specifier. A program bound to :: will be given traffic for any actual IPv6 address assigned to the system - it may also receive IPv4 traffic too in the form of IPv6-mapped IPv4 addresses (::ffff:x.x.x.x) although this is ...
options inet6 sets RES_USE_INET6 in _res.options. This has the effect of trying a AAAA query before an A query inside the gethostbyname(3) function, and of mapping IPv4 responses in IPv6 "tunneled form" if no AAAA records are found but an A record set exists. Maybe your clients have that option set?
Feb 5, 2022 · 2. If you want to find the public IPv6 address you can do this with the dig command and then pipe the result into the sed command to remove the closing quotes. dig -6 TXT +short o-o.myaddr.l.google.com @ns1.google.com | sed 's|"||g'. Another alternative is using the curl command and pulling the IP address from a URL such as OpenDNS'.
Aug 21, 2019 · The cert's SANs include the IPv4 and IPv6 addresses of the service. I suspect a reason for such a cert is to implement DNS over TLS. Also responsive to https, you can see the cert in your browser: https:// [2606:4700:4700::1111] Implementations supporting subjectAltName but not v6 iPAddress is a bug.
