Many ISPs and end-user firewalls seek to block bogons, because they have no legitimate use (more details on how successful they can be at this are below). But filtering the full bogon list requires about 5000 rules for IPv4 and about 70,000 rules for IPv6. Filtering private IP addresses requires only a few rules.

Simon Leinen (from SWITCHengines) explains their use of IPv6 with OpenStack. Jeff Geerling has a great article on why he returned his 2016 MacBook Pro with Touch Bar ; it’s definitely worth a read, in my opinion. Vivek Gite over at nixCraft explains how to use ufw (Uncomplicated Firewall) on Ubuntu to limit SSH connections.

I highly recommend you read the entire post, but in short the five skills Matt recommends are software skills (which includes configuration management and software development tools like Git ), Linux, deep protocol knowledge, hypervisor and container networking, and IPv6. I don’t think I’ve mentioned this before; if I have, please forgive me.

Tor Anderson has an article on using IPv6 for network boot using UEFI and iPXE. In part 2 Larry walks through the node definitions in Vagrant , and in part 3 he reviews the Vagrantfile and turns up the environment. Larry Smith Jr. has a great blog series going called “Hey, I can DevOps my Network too!”

Anyway, I definitely see the value of a server OS that really can configure the IP addresses automatically, and all you have to do is follow on screen directions. Installation of the DHCP role is straightforward enough until the question of IPv6 is raised. All clients in the network concerned are running Win7 Pro. 3/07/2012 2:07 PM.
