Der Rest in English :-)
Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 3
What happens under the hood
Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 4
Internet layers
Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 5
A network of networks
network A
(AS 1)
network C
(AS 3)
network B
(AS 2)
193.0.0.0
193.0.0.1
193.0.0.2
IP transport protocol
(TCP/IP)
Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 6
Internet infrastructure
• Internet protocols / standards
- TCP/IP, email, ftp, http, ..
• IP addresses / numbers
- IPv4: 193.0.22.0/23
- IPv6: 2001:67:2e8::/48
- Autonomous System Numbers: AS3333
Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 7
Protocols & standards
• The Internet Engineering Task Force
- started in 1986
- independent, not-for-profit
- not even a legal entity
• Anyone can participate
• People participate as individuals
- companies or governments have no special rights
• No voting
- consensus by humming
Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 8
https://ietf.org
• Standard documents available for free
• Very different from other SDOs
Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 9
IP addresses
• Unique identifiers (numbers)
- only 4.3 billion numbers in total
• labs.ripe.net = 193.0.06.153
Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 10
Address distribution
• Addresses need to be unique
- otherwise packets cannot be delivered
• Addresses need to be registered
- so you know who uses what
Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 11
Address distribution
• 1980s: Central distribution
- Jon Postel
- everyone (universities) got a range of addresses
• Didn’t scale
- more de-centralisation needed
Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 12
RIPE community
• Started in 1989 by researchers in Europe
• Technical coordination of IP network
• Volunteers, no legal structure
• Open to anybody
- meetings
- working groups
- mailing lists
• Collaboration and coordination
Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 13
RIPE NCC
• Not-for-profit, independent, neutral
• Started in 1992
• Membership organisation (18,000 members)
Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 !14

Mirjam Kühne | re:publica, Berlin, Germany | 2 May 2018 15
Collaborative model
little government
