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