Table 1. This table illustrates subnet masks. The number after the “/” in the CIDR notation indicates the total number of IP addresses available. Click here to see an enlarged diagram. Understanding ...

Supernetting was created as a way to solve the problem of routing tables growing beyond our current ability to manage the exhaustion of Class B network address space. Much like one area code ...

In my previous post I wrote about all the positives we get from the almost incomprehensibly massive IPv6 address space, all there for our enjoyment if we will just break free of our long-ingrained ...

If they duplicated the subnet, the firewall shouldn't have accepted it. If it did, then it was likely bridging two subnets. If the ISP legitimately wanted to use that RFC1918 subnet, this would still ...
