Objectives of the Project
❑ Create Route Visibility Tool to query delegated resources for following goals:
✓ Check whether the address space has been advertised to global routing table
✓ If there is no exact match, sub-prefixes will be queried for further verification
✓ If there is no match totally, then the address space has not been advertised yet
❑Users of the tool: RIRs such as APNIC, ISPs, and Telecom Operators.
❑It is useful in verifying whether the delegated resources are actually being used.

Resources for the Tool
❑Data sources:
✓ Resource delegation dataset from APNIC
✓ Global routing table
✓ Data from a MikroTik Router, which is set up for this project
❑Data is stored in MSSQL Server for the query.
✓ Resource Delegations
✓ BGP Prefixes

❑This tool can be useful for resource quality assurance.
❑Using this tool, we can verify routing status of the delegated address space.
✓ Fully advertised
✓ Partially advertised
✓ Not advertised
❑Later it can be upgraded to compare the “route” object in whois database for
Route Origin Validation.
Use case I:
Resource Quality Assurance

Use Case II:
Routing Issue
• Users were delegated an address space, but it is not properly advertised to be routable.
• Operators can search by country code or prefix using our tool.
• Team member Russell shared a real issue he faced in PNG:
• PNGUoT (PNG University of Technology) was delegated an IPv4 address space
• PNGUoT did not advertise the entire address space
• PNGUoT would like to find out who is advertising the prefixes of their address space
• This tool can help to quickly verify whether the prefixes are advertised, and if yes, by which
origin AS

Use Case III:
Route Origin and AS_PATH Verification
• Route origin is displayed in the output of this tool, the prefix can be verified
which origin AS it is from.
• AS_PATH is displayed in the output of this tool, ASes along the path that
the prefix traversed can be known.

Flow Chart
How the Tool Works

Algorithm Procedures
1. Start query by Address Family plus country code or specific prefix.
2. Search the Address Delegations table to find out which address space has been delegated.
3. Search the BGP Prefixes table to find out which prefixes are visible on the Internet.
4. If the visible prefix exactly matches the delegated address space, return OK.
5. If there is no exact match, but there are sub-prefixes of the delegated address space,
which cannot cover the entire address space, return PARTIALLY OK.
6. If there is no exact match, but there are enough sub-prefixes to cover the entire delegated
space, return OK.
7. If there is no match totally (no exact match, no sub-prefix), return NOT OK.

Load Delegation Prefixes to SQL Database

Load IPv4 Global Routing Table from
MikroTik Router to SQL Database

Load IPv6 Global Routing Table from
MikroTik Router to SQL Database

Query Fields and Output Display
❑Query Fields:
✓ Address Family
✓ Country Code or Prefixes
❑Output
✓ Status
✓ OK – The prefix is exactly matched between global routing table and resource delegation. Or no exact match, but
sub-prefixes presented, and they can cover the entire address space
✓ PARTIALLY OK – Sub-prefixes presented in global routing table, but not fully covering the entire address space
✓ NOT OK – It is not advertised
✓ Origin AS and AS_PATH

Tasks to Do
❑Setting up Microsoft SQL Server database.
❑Setting up the MikroTik Router.
❑Program functions for loading data from sources to the database.
❑ Prefix Delegations from APNIC
❑ BGP Prefixes from global routing table
❑Program functions for performing the comparison.
❑Application development with C#.
• Thanks and appreciate the help from our team mentor and all team members ☺

Further Development
❑Web GUI.
❑Route Origin Validation with “route” object and ROA data.
❑Integration with multiple routing platforms.
❑Currently we have done with MikroTik RouterOS only
❑Data source expansion:
❑Include Address Delegations data from other RIRs
❑Include BGP Prefixes data from other parties (everyone can participate)

/ipv4-by-country PG 2

Search IPv4 by Country
(PARTIALLY OK)

Search IPv4 by Country
(NOT OK)
Search IPv4 address delegations and routes in
PG (Papua New Guinea), show only results
