Re: Disable IPv6 ?

It's not just me by the way, it is IBM's opinion also that if you do not use IPV6 inside your network you should disable IPV6 on IBM i.

If you are rolling out IPV6 in your network then you will be doing your homework, and validating that all your applications work correctly with IPV6 on a test partition before you crank it up on your production partition. In that case by all means, crank it up. Until you have done that however my recommendation stands: Disable it.

I was surprised by your opinion, since you are one of the more reliable
references in Midrange.

Having an important application that does not support IPv6 is a reason
to disable it, but that is not a general rule, and it is very likely
that a newer version will work fine with IPv6.

Respect to the "inside network" other advise is to use IPv6 only, and
translate to IPv4 in the edge devices if your ISP provider is IPv4 only,
or leave to the ISP to do the translation.

Well for one if you run ZendServer and their MySql it will randomly
just quit if IPV6 is running so that is a bad thing. Other services
also don't work without specific configuration when IPV6 is enabled.
Inside your network do you really need IPV6? Most do not.

What's the point of enabling IPv6 on your edge devices if you disable it
on IBM i? So your Linux and Windows systems can use it? I suppose if
your
IBM i is not able to be reached from the internet, that's a reasonable
recommendation, though.

Remember that most of those recommendations are to disable IPV6 on
IBM i

for local use. This is not the same as disabling IPV6 on your edge
devices such as routers or firewalls. Completely different animal.

As far as I am concerned this recommendation still applies.

In this list I have seen several times advise to disable IPv6 as
solution to slow network. Not lately, but at that time I replied that

it

seems to me a very bad advise.

Today there was a "first" for IPv6, see:
