At last, a small set of unicast addresses have been defined for special use. They do not carry a scope, so they are discussed independently of the other unicast addresses. Two basic addresses carry ...

The IPv6 transition in your organization, more likely than not, involves bringing IPv6 into a mix that also includes IPv4. Here’s a look at what that means and how to make it work. The original title ...
