IPv4 addresses became scarse so we will not waste any for the host systems virbr1 or eth0. The following diagram illustrates my IPv4 setup of a simple arp proxy utilizing ipv4 forwarding. The guests use their public ipv4 addreses and the ips of the hosts gateway. -{.img-fluid} +{.img-fluid} There is no need to save address space in case of IPv6 since we have a complete /64 IPv6 subnet at our disposal. While only a few guests are accessible by their IPv4 public addresses directly, we have virtually an infinite number of IPv6 addresses. Sidenote: One single /64 IPv6 subnet consists of 2^64 different addresses, which is over four billion times more than there are IPv4 addresses in the whole world! I use just the lower /65 half of our /64 subnet for the guests while the IPv6 address of the hosts NIC lies in the upper half. |
