Getting Internet Number Resources from ARIN

Community Use Slide DeckCourtesy of ARIN

Internet Number Resources• Internet Protocol (IP) Addresses– 2 types: IPv4 & IPv6– Uniquely identifies a device on a

network–Moves info on the Internet

• Autonomous System Numbers (ASNs)– Used by network operators– Controls routing within networks– Exchanges routing info among ISPs

2

History of the Internet Protocol• Internet Protocol version 4 (IPv4)

– Developed for the original Internet (ARPANET) in 1978– 4 billion addresses– Deployed globally & well entrenched – Allocated based on documented need

• Internet Protocol version 6 (IPv6)– Design began in 1993 when IETF forecasts showed IPv4

depletion between 2010 and 2017– 340 undecillion addresses– Completed, tested, and available since 1999– Used and managed similar to IPv4

3

ARIN’s IPv4 InventoryARIN still has IPv4 addresses remaining

IPv4 inventory published on

ARIN’s website: www.arin.net

Updated daily @ 8PM ETx.xx

ARIN’s IPv4 Countdown Plan• Process for final IPv4 requests– Divided into four phases– Length of each could vary• Global policy to return space to IANA• Faster depletion due to:

– Large requests– Policy changes X.XX

5

Qualifying for an Autonomous System Number (ASN)• Confirm multi-homing

within 30 days• Provide verification of connectivity

with two or more ISPs– Signed connectivity agreement– Recent bill/invoice

6

Internet Service Provider (ISP) vs End-user

• ISP– Assigns address space to the users of the

network services it provides– Other ISPs and end-users are customers

• End-user– Receives assignments of IP addresses

exclusively for use in own operational networks

7

Connections to ISPs

8

You are single-homed if you have 1 ISP

You are multi-homed if you have 2+ ISPs

Qualifying for IPv4as an ISP

• Multi-homed– Two /24s reassigned to you– Data to show 2 /24s efficiently used

• Single-homed– 16 /24s reassigned to you– Data to show 16 /24s efficiently used

• Immediate need

9

Typically Requested IPv4 ISP Data

• Mapping of static IP addresses/subnets to customer names– May include customer justification

• List of all dynamic pools with prefix/range assigned, area served, utilization percentage

• Mapping of internal subnets with description and # IPs used

10

Three-month Supply Calculation• Justified need, not solely predicted

growth• Utilization rate of last allocation• Immediate need for exceptional

circumstances

11

Qualifying for IPv4 as an End-user

• Multi-homed– 64 IP addresses used immediately– 128 IP addresses used within one year

• Single-homed– 1,024 IP addresses used immediately– 2,048 IP addresses used within one year

12

Typically Requested IPv4 End-user Data

• Subnet mapping showing each subnet to be created and for each subnet– Description of its purpose–# IPs used within 30 days–# IPs used within one year

13

Qualifying for IPv6 as an ISP• Have a previous v4 allocation from

ARIN• Intend to multi-home• Provide a technical justification which

details at least 50 assignments made within five years

14

Typically RequestedIPv6 ISP Data• If requesting more than a /32,

a spreadsheet/text file with–# of serving sites (PoPs, datacenters)–# of customers served by largest– Block size to be assigned (/48 typical)

15

Qualifying for IPv6as an End-user• Have a v4 direct assignment• Intend to multi-home• 2000 IPv6 addresses or 200 IPv6

subnets used within a year• Technical justification as to why

provider-assigned IPs are unsuitable

16

Typically RequestedIPv6 End User Data• List of sites in your network– Site = distinct geographic location– Street address for each

• Campus may count as multiple sites– Technical justification showing how

they’re configured like geographically separate sites

Qualification for Address Space Based on ARIN Policies

19

• Open– Developed in open forum– Anyone can participate

• Transparent– All aspects documented and available online

• Policy process, meetings, and policies

• Bottom-up – Policies developed by the community– Staff implements, but does not make policy

Policies at ARIN

20

• Policy Development Process (PDP)– Describes the process for making

policies in the ARIN region• https://www.arin.net/policy/pdp.html

• Number Resource Policy Manual (NRPM)– ARIN’s Policy Document• http://www.arin.net/policy/nrpm.html
