Reserved IPv4

  • /13: temporary assignments
  • Approx. /16: Internet Exchange Points (IXPs)
  • Of /15 reserved for this purposes
  • With the current rate, enough for 10 years more
  • /13: quarantine
  • Will be allocated later
  • IPv4 dust

  • Supported by the IPv4 policy
  • First, you have to become LIR.
  • Only if you did not already get an

allocation from the RIPE NCC

Addresses being returned

  • Continues after run-out
  • Closures
  • Recovered space: approx. 2000 /24s in 2019

  • Trading in IPv4 is inevitable
  • Priority accurate registry
  • Current policy:
  • IPv4 transfers are allowed
  • 24 month holding period

Transfers: RIPE community 2012 response

  • You have to have a LIR status to get a PA block
  • PI cannot be used to make further assignments to other

parties.

  • Both IPv4 and IPv6
  • Even 1 address
  • Thus, PI is suitable for Internet resources, but for ISPs
  • There was no strict control over this rule, but it can be invented

PI vs PA

IPv6 in Ukraine

  • The grows just

started

  • Current level is

sufficiently lower than the world average: 27%, according to Google

  • IPv6 operators:
  • Netassist
  • ITL.ua
  • Triolan
  • ?

IPv6 in Ukraine

  • There are powerful reasons for such a low IPv6 penetration
  • However, nursing these causes instead of trying to fight them

will now lead to operational problems for operators

  • It is easies for content providers, and they can help telecom
  • perators
  • Content over IPv6 saves money on NAT/CGNAT expanding

Count only local resources Include global resources (Google, Facebook etc)

  • It makes perfect

sense for operators to implement IPv6

  • The most popular

resources are IPv6- enabled (Google, Youtube, Facebook)

  • Cloudflare helps
  • Most of local

resources do not see the reason to turn IPv6 on
