01 / you
It starts here
Everything online travels in small packets. Yours sets off right here, from your own screen, and goes to your internet provider first.
02 / on the way
Network to network
The internet is more than 70,000 separate networks. Over BGP they tell each other which addresses they can reach, and that's how traffic finds its way. Below: the networks between your provider and mine.
Traffic enters my network through bgp.rodeo (AS202585), my link to the rest of the internet, or through ENS-IX in Enschede.
03 / Enschede
AS218369
My own network, with its own number and its own IPv6 addresses. A virtual router in a data centre in Enschede tells the rest of the internet that those addresses belong to me. That router also has a port on ENS-IX, the exchange where networks hand traffic straight to each other.
04 / Hengelo
This page lives here
My network sits in Enschede. This page runs one town over, on an HPE ProLiant DL380 G9 in Hengelo. Proxmox splits that server into virtual machines. In one of them, Traefik passes each request to the right container, like the one for this site.
05 / desk
I'm Kevin
At an enterprise telco, I keep networks and servers running. Outside that job I build my own platform and my own network. They run in Enschede and Hengelo. My desk only holds what I need to reach them.
06 / work
What I build
Four projects. One is for my employer, the rest are mine.
- 01Tieman IT platformMy own hosting platform on Proxmox and Docker. Shipping a client site takes one command, and monitoring runs around the clock.
- 02DC migrationA data centre move for an enterprise telco: three server clusters, with an IPv6 backend.
- 03AS218369My own network, with transit from bgp.rodeo and a port on ENS-IX. Routes that fail RPKI don't get in.
- 04tieman.itMy company. I build webshops and web apps for small businesses and host them myself.
