2. Essential Facts
“One of the RIPE NCC's key responsibilities as a Regional Internet Registry is to keep the RIPE Registry correct, complete, and up-to-date”
Keeping registration data current:
Helps network operators to make better operational decisions
Prevents resources from being hijacked
General intro of what you are going to talk about.

3. Legacy Internet Resources
Distributed before (or outside of) the current system of hierarchical distribution by the RIRs
Have been kept outside any formal relationship between their holders and the RIPE NCC
The RIPE NCC:
Maintains and publishes registry data for resources held by members and legacy Internet resource holders
Provides reverse DNS delegation and a routing registry for IP addresses and AS Numbers, both of which include legacy Internet resources
General intro of what you are going to talk about.

4. Where You Come In
Academic & research institutions were among the pioneers of the Internet in our region
Big part of legacy resources reside within the R&E community
Undocumented redistribution of legacy resources led to many legacy holders not being aware nowadays of the resources they hold
Registration data is often out of date, making the resources vulnerable for hijacks
General intro of what you are going to talk about.

5. Legacy Resources in the R&E Community
1,849 IP blocks
469 AS Numbers
In total: 2,318 out of 4,730 legacy resources are within R&E
General intro of what you are going to talk about.

6. RIPE Policy & Options The policy: Options for legacy holders:
was implemented on September 2014
Establishes the principles to be applied in offering and implementing registry services for legacy holders
Options for legacy holders:
Register resources with their LIR (if already a RIPE NCC member)
Become a member of the RIPE NCC
Engage via a sponsoring LIR
Engage directly with the RIPE NCC
Choose not to establish a formal relationship with the RIPE NCC
General intro of what you are going to talk about.

7. We‘d Like You to Remember…
Protect against hijacking
IPv4 addresses become more vulnerable as they become more scarce
Hijackers try very sophisticated methods to obtain control over (apparently) unused address blocks
Faking registration and identity papers. Faking entire websites and domains
Good practice:
Keep your data in the RIPE Database accurate and up-to-date
If transferring resources, ensure you are in contact with a legitimate representative of the organisation
For all legacy issues, get in touch with the RIPE NCC if you need help or have questions
