All browsers currently fail to parse all of those examples. ![]() I'm concerned that if we decide to use "%25" as the delimiter to indicate the beginning of a zone id, some software will interpret "25eth1" to be the zone id and some will interpret "eth1" to be the zone id. NSURL seems to be ok with " and " but not " "fe80::abcd%25eth1" seems to be the most parsable of those examples in my sample of 2 IPv6 host parsers. Inet_pton seems to be ok with "fe80::abcd%25eth1" and "fe80::abcd%eth1" but not "fe80::abcd-eth1". Here are a few thoughts I have on this, without indicating support or opposition: I am not denying that, however the same is true for IPv4 - you can easily scan .y/24.Įven with this inconsistent security claim in mind, I ask the mozilla developers to at least include support for link local with something on the line of about:config->ipv6-allow-link-local: to not stop all network engineers from working.Ĭan we reopen this bug or create a new one for realising this? I often hear the argument that with link-local addresses it would be possible to do Javascript based LAN scanning. So we are basically in the situation that the link local address is the only reliable address that can be used to configure a whole class of devices.
