Carla Schroder shows how to set up automatic IP address configuration for unique local addresses.

IPv6 Auto-Configuration in Linux

In Testing IPv6 Networking in KVM: Part 1, we learned about unique local addresses (ULAs). In this article, we will learn how to set up automatic IP address configuration for ULAs. When to Use Unique Local Addresses Unique local addresses use the fd00::/8 address block, and are similar to our old...

IPv6 networks
To continue our series on IPv6 private addressing, this article shows how to use KVM to create networks for testing IPv6.

Testing IPv6 Networking in KVM: Part 2

When last we met, in Testing IPv6 Networking in KVM: Part 1, we learned about IPv6 private addressing. Today, we're going to use KVM to create networks for testing IPv6 to our heart's content. Should you desire a refresh in using KVM, see Creating Virtual Machines in KVM: Part 1 and Creating...

In this two-part series, we will learn about IPv6 private addressing and configuring test networks in KVM.

Testing IPv6 Networking in KVM: Part 1

Nothing beats hands-on playing with IPv6 addresses to get the hang of how they work, and setting up a little test lab in KVM is as easy as falling over — and more fun. In this two-part series, we will learn about IPv6 private addressing and configuring test networks in KVM. QEMU/KVM/Virtual Machine...

Carla Schroder looks at two handy IPv6 calculators along with some tricks for subnetting.

Calculating IPv6 Subnets in Linux

We're going to look at some IPv6 calculators, sipcalc and subnetcalc, and some tricks for subnetting without breaking our brains. Let's start with reviewing IPv6 address types. There are three types: unicast, multicast, and anycast. IPv6 Unicast The unicast address is a single address identifying a...

Learn about ipv6calc -- the excellent IPv6 address manipulator and query tool that packs a ton of functionality.

Manipulate IPv6 Addresses with ipv6calc

Last week, you may recall, we looked at calculating network addresses with ipcalc. Now, dear friends, it is my pleasure to introduce you to ipv6calc, the excellent IPv6 address manipulator and query tool by Dr. Peter Bieringer. ipv6calc is a little thing; on Ubuntu /usr/bin/ipv6calc is about 2MB,...

This screenshot of /etc/protocols shows the correct protocol names to use in iptables rules; get details from Carla Schroder in this tutorial.

How to Write iptables Rules for IPv6

We US-ians have been sheltered from the exhaustion of IPv4 addresses, but they have run out. IPv6 networks are up and running, so we have no excuses for not being IPv6 literate. Today our scintillating topic is iptables rules for IPv6, because, I am sad to report, our faithful IPv4 iptables rules...

Firewall rules
Carla Schroder starts this short series on firewalls by debunking some common IPv6 security myths.

Building IPv6 Firewalls: IPv6 Security Myths

We've been trundling along nicely in IPv6, and now it is time to keep my promise to teach some iptables rules for IPv6. In this two-part series, we'll start by examining some common IPv6 security myths. Every time I teach firewalls I have to start with debunking myths because there are a lot of...

Old file-copying tools like SCP, SSH, and Rsync are all IPv6-ready, but they have syntax quirks you need to know to make them work.

Remote Sessions Over IPv6 with SSH, SCP, and Rsync

Our familiar old file-copying friends SSH, SCP, and Rsync are all IPv6-ready, which is the good news. The bad news is they have syntax quirks which you must learn to make them work. Before we get into the details, though, you might want to review the previous installments in our meandering IPv6...

If you want your computers to talk to each other then you must know about routing; we're here to help clear the way.

Practical Networking for Linux Admins: IPv6 Routing

Our story so far: We have learned the important bits about TCP/IP, IPv6, and IPv4 and IPv6 LAN Addressing, which is all very excellent. But, if you want your computers to talk to each other, then you must know about routing. Simple Test Lab Now we have a good use for the ip command. ip assigns...

Learn the basics of private and link local addressing in this tutorial from Carla Schroder.

Practical Networking for Linux Admins: IPv4 and IPv6 LAN Addressing

We're cruising now. We know important basics about TCP/IP and IPv6. Today we're learning about private and link-local addressing. Yes, I know, I promised routing. That comes next. Private Address Spaces IPv4 and IPv6 both have private address spaces. These are not meant to leave your private...
