This is the first of many technical blog posts I’m going to post on IPv6 architecture and implementation for a Microsoft Windows-based environment. I started off with a basic introduction of the IPv4 ...

Today, the standard methods for moving the network/host address boundary are variable-length subnet masking (VLSM) for host addressing and routing inside a routing domain, and classless interdomain ...

In addition to IPv4 (often written as just IP), there is IP version 6 (IPv6). IPv6 was developed as IPng (“IP:The Next Generation” because the developers were supposedly fans of the TV show “Star Trek ...

OK, so I have a subnet (192.168.11.0) that currently has all servers and clients on it. It's running out of addresses. So, I create a new subnet (192.168.12.0) and change my DHCP server (Fortigate ...

To understand how subnetting works, you first must have a good basic understanding of IP addresses. An IP address is set of binary octets broken into quads. That definition may not have made any sense ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Table 1. This table illustrates subnet masks. The number after the “/” in the CIDR notation ...

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 your company network is having problems and you need to troubleshoot it, you also need to know some basic information about the computers on the network. Internet Protocol is the underlying ...

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 ...

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 ...
