I've added charms.openstack to the affected projects because, at present, and reactive charms based off charms.openstack will only support memcache on ipv6 (and not ipv4). This affects at least designate, manila, and barbican.

Add memcache support for ipv4

    charmhelpers was recently updated to support ipv4 for
    MemcacheContext if no ipv6 network is available. This change adds the
    same functionality to the charms.openstack library, which means that
    it can be used (automatically) by charms.openstack based charms.
    e.g. designate, manila, barbican, etc.
