Is there some sort of shortcut one can use when doing basic troubleshooting with IPV6? In the old days it wasn't terribly difficult to remember a few key IPV4 address and be able to relatively easily ping them or telnet to them.
For the moment I am experimenting with IPV6 and have purposely choosen a very simple (read: lots of zeros) address scheme. For instance right now I can fairly easily ping fd::1 and fd::2 and so on. But what happens when I get a "real" IPV6 from an ISP?
It would be great if one could skip the network portion of the IPV6 address using something like DNS suffix search order to ping host1 rather than host1.mydomain.com. In this case instead of pinging 2008:6ce5:0e6b:f561:aaaa:bbbb:cccc:dddd I would simply ping aaaa:bbbb:cccc:dddd because the network part was somehow configured or implied. Does something like this exist?
Is this feature available in IPv4, No of course because you must specify the entire IP address to communicate so the same goes for IPv6.
The first /48 are assigned by ISP then the bits from 49 to 64 are used to subnet so you ar going to use a simple to remember scheme and the host part unless you staically configure it is derived from the MAC address so it is the most complicated part to remember not the prefix part.
Just a point of correction. There are RFC 1918 style address in IPv6 they are called Unique-Local (fc00::/7)
So a way to adapt your shortcut proposal would be to preface the intended IPv6 address with the FD00 prefix.
ip address 172.16.1.1 255.255.255.0
ipv6 address fd00:172:16:1::1/126
However, the purpose of Unique-Local is to provide an expectation of private uniqueness within a network and not have addressing overlap should there be a merger at some point in the future. If people were to adopt this shortcut in production it would defeat the purpose of this address space, this is best kept to a lab setup / environment.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
