Running my own AS

Disclaimer

• dont do this just to do it (if everyone does this, the internet probably falls apart)
• you can get v6 space fomr some people if you just need addresses

Experience and Learnings

Questions I had upfront

How long does it take?

What does it cost?

• many different configurations
  • dont need ASN
  • dont need PI (can use PA, which is often included or really cheap)
• ASN + PI: ~180€ per year (for me…)
• routers
• probably want a domain
• transit?
• maybe even datacenter and/or

Dual Stack?

No.

I mean, I would love to have some IPv4 Space, but since we ran out of available addresses and buying address space starts at roughly 10k, no. Some single rented address from a hoster must be good enough for now.

What accounts do I need?

• PeeringDB
• BGP.tools useful, but not required

Links to read all about this

• ken finnegan
• bgp.tools rumschauen

Last but not least, you can get a lot of inspiration form looking at bgp.tools and PeeringDB entries.

Open TODOs

Well, where do I start and where do I end? Running your own AS with your own IP space opens a lot of possibilities

• Second Router
• Monitoring
• Maybe better upstreams with shorter latency
• RPKI
• Automatic collection of router configs
• DNS Servers (authoritative and resolvers)

Maybe in the far future:

• Peering
• Physical router
