What it is like to have your own IPv6 and IPv4 space

November 28, 2019 | HE | No Comments

Hey everyone,

As some of you know, I have my own IPv4 and IPv6 subnet, along with my own Autonomous System Number, in my case AS208751.

I am not a LIR (Local Internet Registry, you can read more about that here.) myself, so I had to get a sponsoring LIR to request my ASN. Once that was taken care off, I got myself a /44 IPv6 subnet, and a /24 IPv4 subnet.

As I am writing this, the RIPE NCC announced here that they ran out of IPv4 addresses, so I hope that the price that I pay for it does not get too high, otherwise I will have to let go of it.

It is an adventure, at least for me, to get it working. Especially BGP, as I had rarely worked with that before (I did in a GNS3 lab environment), but it’s different when you are peering with actual companies. (In my case, Hurricane Electric and Choopa LLC.)

Hurricane Electric provides a free BGP tunnel for IPv6, and Vultr provides a free dualstack BGP when you get a VPS with them.

I’ve managed to set it all up, and as you can see here, it’s all working!

I use frr on Ubuntu Server to set it up and it works fine. For encapsulation, I use a mix of GRE, as well as Foo over UDP with GRE in it. (The latter is thanks to a firmware bug in my ISP’s modem.)

Sometimes I watch the traffic, and see lots of ports being scanned. Especially from Shodan and Censys scanners. But also from AWS/Azure/GCP instances and servers in China and Russia.

Currently, I am trying to get it to work so I can use some IPs with NSX-T’s Tier 0 routers. This is something that I am still working on and will make a blog post later once I’m done working on that. (this idea worked and I have now abandoned it.)

That marks the end of this post, thank you for reading it and see you all for the next post.

A much needed personal and VMware lab update

November 25, 2019 | VMware | No Comments

Hello everyone,

Here’s an update on both my personal and lab situation. First of all, thank you for the few that have send me an email giving some advise and such. It is very much appreciated.

Luckily, I am now able to go to a place where I get to work with servers and networking. They’ve even asked me to set up a VMware stack on a budget. So that will be fun, and I will be sure to make blog posts out of it. The first one is coming this Wednesday hopefully. Other than that, I’ve been doing better. Slowly getting off my medicine, which is nice too.

On the VMware side, I have almost successfully moved from NSX-V to NSX-T. Many thanks to the people over at the VMware Technology Network forums. They have been helping me a lot over there. I will also be making a post of how I moved from NSX-V to NSX-T and how it is to use NSX-T after using NSX-V for a while. You can read more about NSX-T here, and the differences between NSX-V and NSX-T here.

Thank you for reading this blog post and see you all soon.
