Feature added by: Lars Müller (lmuelle) Feature #313312, revision 1 Title: Avoid duplicate use of IP addresses openSUSE Distribution: Unconfirmed Priority Requester: Desirable Requested by: Lars Müller (lmuelle) Partner organization: openSUSE.org Description: We have to consider to change the default setting /etc/sysconfig/network/config:CHECK_DUPLICATE_IP to "yes". DAD (Duplicate Address Detection) is recommended by RFC 2131. See also RFC 3927 and 5227. This is how Microsoft handles it since Windows NT version 4.0 Service Pack 3. If I get it right Apple follows this approach too. -- openSUSE Feature: https://features.opensuse.org/313312
