Hello, I'm in the process of reviving ipv6 on our network. I'm new to IPv6 so this questions is perhaps obvious. I found an old company document which lists the following format for an IPv6 address. | 16 | 19 | 13 | 16 | 64 bits | +-+---------+------+-----------+--------+-----------------+ | 0x2001 | sTLA | NLA | SLA ID | Interface ID | +-+---------+------+-----------+--------+-----------------+ I'm confused here, reading RFC2373 I found the folowing format |3| 13 | 8 | 24 | 16 | 64 bits | +-+---------+-----+------------+--------+-----------------+ | | TLA ID | RES | NLA ID | SLA ID | Interface ID | +-+---------+-----+------------+--------+-----------------+ Hmmm, what's wrong. -Jeroen- -- Jeroen Valcke sst@belnet.be jeroen.valcke@belnet.be
