What steps will reproduce the problem? 1. memcached -l ::1

What is the expected output? What do you see instead? - Expected is that memcached binds to the interface

• Actual result Invalid port number: ":1"failed to listen on TCP port 11211: Success

What version of the product are you using? On what operating system? 1.4.15 on Ubuntu 12.04

It does work in Debian 6.0 (memcached 1.4.5) but not with anything newer I tested...

Please provide any additional information below.

Work around is to use an IPv6 only DNS name as parameter to L

Hello,

The same issue. I can't bind an ipv6 address.

Please help.

Pull request https://github.com/memcached/memcached/pull/98

allows to specify IPv6 address without port or IPv6 address enclosed in [] with or without port (RFC3986 style recommended by RFC5952)

-l IPv6 -l [IPv6] -l [IPv6]:port

This is a serious defect/flaw. When will it be fixed in an official release?

Same problem here! I am unable to run memcached in a Dual-Stacked network environment!

I know that it's not really a solution and this still needs to be fixed, but running memcached on 127.0.0.1 and haproxy on external ip's with 127.0.0.1:11211 as a backend is a workaround. Op 22 feb. 2015 03:22 schreef :

Why it isn't a "real solution"? I'm planning to put this into production... Is it not recommended?

I REALLY need to bind memcached on an IPv6 address, since my networks are already IPv6-Only.
