How to support 50K IPv6 addresses on a single machine?
Does anyone know if there is any way to configure 50K "virtual" IPv6 addresses on loopback device in Linux?
The aim is not to add all 50K IPv6 addresses one by one on the loopback/ETH device which will probably mess up the ip table on the system.
In IPv4, I am able to achieve that by specifying the IP address subnet on loopback device (e.g: "ip addr add 10.1.0.0/16 dev lo").
The same command does not seem to work the same way for IPv6. It only adds a single IPv6 address on loopback device and it automatically adds an "unreachable route" entry on the ipv6 route table for that IPv6 network prefix.
The reason I need this is because I am working on an application which tries to simulate 50K IPv6 addresses on a single Linux box.
The kernel version I am currently using is RHEL 22.214.171.124.
Any help would be greatly appreciated!!
