Inet6 fe80::216a:2b1d:c908:eb39/64 scope link noprefixrouteĮvery time I rebooted, the xxxx… was the same, but the rest of the address was different. Inet6 xxxx:xxxx:xxxx:xxxx:a5e4:61a:b3b2:9d8b/64 scope global dynamic mngtmpaddr noprefixroute. On the server machine, the addresses were wlxd037450ab7ac: mtu 1500 state UP qlen 1000 A connector can have more than one address. On Linux I can use the ip -6 addr command to display the address of the connection. Where GUA is the Global address (known outside of my network). I have 2 Laptops and a Server all running Linux.įrom my internet router I could see the information for LT2 So instead of giving real IP addresses, Ive used xxxx:xxxx:xxxx:xxxx for the IP V6 address provided by my Internet Service Provider, and using the 2001:db8::/64 address which is assigned for documentation use. One site gave me the top part of my post code, the latitude and longitude of my garage, and my ISP provider. There are sites which can give you your geographic location from your IP V6 address. ROUTE 2001:db8::7/128 fe80::cccc IFPORTCPĪs part of understanding how IP V6 dynamic routing works, I managed to get my little home network to talk using IP V6. You then put this address into the z/OS routing statements. To get round this problem you need to explicitly define an address on Linux sudo ip -6 addr add fec0::cccc/64 dev tap1 On z/OS you defined a route using this IP address, for example BEGINRoutes This explains why the connection was getting a different IP address every time I ipled. The connection between Linux and z/OS is a “tap” interface (a kernel virtual device) which looks like an OSA adapter to z/OS.Įach TAP device has a random MAC address that is used as source address.
On many systems, this value does not change across IPLs – and so most of the documentation uses the “constant” value. IP V6 address for use within a connection are like fe80::b0b6:daff:fe64:77f5 where b0b6:daff:fe64:77f5 is based on the MAC(hwaddr). I could not understand why configuring the IP V6 link between Linux and z/OS was so difficult. I was looking into configuring IP V6 on my z/OS running on zPDT running on Linux.
