HE Sage Certification

July 26, 2019 | Certification, HE, IPv6, Networking | No Comments

Hi readers,

This post will be all about Hurricane Electric their IPv6 certifications.

Myself, I recently got the Sage certifications (currently waiting for my shirt to be delivered) and I learned a lot from it.

There are different levels of the certifications. You have practical questions, where you have to setup IPv6 on your server, and you have technical tests, which consists of technical questions about IPv6.

IPv6 is importan. IPv4 is getting exhausted. IANA already allocated all of the IPs that it can. (without having to do a major re-vamp of the internet, for example, having to allow 240.0.0.0/4 -currently a reserved address space, former class E network-, would require a major update for all of the infrastructure, so this won’t happen most likely.)

It is important that more people learn about IPv6 and that it becomes adopted widely, as it won’t take long before all RIRs do not have any IPs left. (Like ARIN).

As a bonus, if you get the Sage certification, you get a shirt!

Thank you for reading this and I hope that you will enjoy the HE IPv6 certification as much as I did.

Thank you for reading.

IPv6 and BGP adventure

July 18, 2019 | BGP, HE, Networking | No Comments

Hi readers,

This post will be about my ‘adventure’ of getting my own AS number, IPv6 subnet, and peering with Hurricane Electric to announce my IPv6 subnet over a 6to4 tunnel.

I started to chat with someone on Discord about getting my own IPv6 subnet. They’re not that expensive. I got mine from SnapServ. I purchased a /44 IPv6 subnet and an Autonomous System Number.

After having successfully set-up a 6to4 tunnel with Hurricane Electric before, I decided to sign up for a BGP tunnel, so I can use my own IP address space.

I got my ASN and /44 subnet from SnapServ. A /44 IPv6 subnet is 16 /48 subnets, and the /44 is that smallest that they had. It’s very affordable.

My AS currently peers with Hurricane Electric. Though this may change soon, as their support has been ignoring my tickets, twice. There is an update of that coming later.

Currently I’m getting packet drops from their tunnel… So we will see how it goes.

For now: made two tickets, got ignored on both my their support staff.

To be updated..

My server

June 22, 2019 | Networking, Virtualization, VMware | No Comments

Hi readers!
Welcome to my first real blog post! In this post, I will be explaining my current server, my trusty HP ProLiant DL380G6.

It’s armed with two Intel Xeon X5650s, which each have 6 core and 12 threads, making it a total of 12 cores and 24 threads. It has 144 GB (18x 8GB) of ECC RAM, and it currently have two 500GB SSDs, along with a single 320GB HDD.
Here is a picture:

Not the sharpest picture, because it was made from quite a distance with my Galaxy J7.

It runs VMware ESXi 6.7 on it, along with a vCenter Server Appliance and NSX. Here is a screenshot of the VM view in vCenter:

I run my firewall on it, which is OPNSense. I previously used pfSense, however it was being buggy with my BGP tunnel for IPv6 (more about that in this post.)

Other than that, I run WDS and MDT on it, so I can easily install Windows over the network. I have my GNS3 VM on it, so I can have it running 24/7 and can access it from anywhere, I use it to learn networking. (More about that in this post.)

I have a Discord Bash bot VM on it, it’s just a python bot that I’m making, to leanr python. Next to that I have a Linux and Windows Workstation VM, that I can login to when I’m not home. ix90 is a bit of a weird project that I’m going into more detail off here.

Everything connects to an Ubiquiti EdgeSwitch 24 Lite. My parents their network runs on a UniFi Security Gateway and a UniFi 8 port POE switch. The EdgeRouter X is just there for me so I can test things with it. Here are some pictures:

That’s a quick overview of my basic networking setup, this post will later be updated with everything about NSX when I have that working.
