how many addresses can have the eth0?

[chandro]

i have installed on my server the ipv6.

and added 50 secondaries, and all respond to ping and trace.

but my question, how many ipv6 can handle the eth0??

100, 1000? more?

thanks.

As many until memory/kernel/I\O limitations are reached.

ok, and is there a way to know the limits before pushing it with to many addresses??

a formula o something??

[cconn]

might be helpful to know what OS and version  ;)


do you plan on never re-using the same IP twice?   :D

Write a script and do it until it fails to allocate any more, and log it all locally or remotely? Again, depends on a bunch of factors like available ram, kernel/os version, nic driver flaws, etc.

If you're using 50+, you beat me.  I'm only using 27 anycast IPv6 addresses each currently on two interfaces (in a virtual hosting environment).

I think you might hit a limit with firewall rules before you'll hit any limit on addresses.

well, i think is not needed more than 100 different ipv6 addresses, even if you want to put one on each domain, for what? nothing is changhing until ipv4 still being the same ip or shared for the domains.

so is ok, im going to keep those 5X added and learn more about what to do with a ipv6 =)
