Global R&E Network Routing Report

Latest Data: 20:31 GMT Thursday February 20, 2025

This summarises BGP data collected from PREGINET's network in Philippines.

Background

PREGINET is the Research and Education network of the Philippines. More info about PREGINET is available on their website.

Summaries

• Analysis Summary, basically the header of the daily e-mail.
• Prefixes visible from AfriNIC, APNIC, ARIN, LACNIC, and RIPE NCC address blocks.
• Address span per AS Globally, AfriNIC, APNIC, ARIN, LACNIC, and RIPE NCC. These are the ASNs who are originating the most address space to the Internet.
• Prefixes announced from AfriNIC, APNIC, ARIN, LACNIC, and RIPE NCC region ASNs.
• League table of number of prefixes announced per ASN Globally, AfriNIC, APNIC, ARIN, LACNIC and RIPE NCC. These are the ASNs who are contributing most to the size of the Internet Routing Table.
• Detailed table of prefixes per ASNs.
• League table of the possible Aggregation savings per ASN Globally, AfriNIC, APNIC, ARIN, LACNIC, RIPE NCC. These are the ASNs who are the biggest polluters when it comes to what they announce to the Internet.
• League table of the possible percentage Aggregation savings per ASN Globally, AfriNIC, APNIC, ARIN, LACNIC, and RIPE NCC. These are the ASNs who, as a percentage of their total announcements, contribute most unneeded prefixes to the Internet Routing Table.
• Looking at the possible aggregation, here are the CIDRisation possibilities per ASN.

Things that shouldn't be here

• Unassigned addresses being advertised (with origin & transit ASNs)
• Unassigned addresses being originated by unassigned ASNs (with transit ASNs)
• Unassigned, reserved and private ASNs in use
• Prefixes from the Special Purpose Address Registry (RFC6890)
• Unregistered ASNs
• Bogon ASNs, the prefixes announced, and their paths.

Other data

• Prefixes longer than /24 and their Origin ASN
• Number of prefixes announced per prefix length
• Number of /24s announced per /8 block
• Number of prefixes per /8 block
• Number of ASNs announcing less than 20 prefixes
• Table of advertised prefixes smaller than registry allocations listed by ASN
• Table of advertised prefixes smaller than registry allocations (per /8 block)
• Number of prefixes transited per AS
• Prefixes originated by 32-bit ASNs

Maps

• Map of assigned /24s (per /16)
• Map of assigned ASNs

Misc Data

• /8s allocated to the RIRs. Just repeats the IANA allocation file really.
• IPv4 prefixes and their origin ASNs
• IPv4 prefixes and their AS Paths
• IPv4 announcements using deprecated AS_SET
• ASN to name mapping for ASNs visible on the Internet today.
• Dump of the Global R&E IPv4 table as seen by PREGINET.
• IPv4 MTR from the Collector to BGP feed source.

RPKI Invalids

• Current IPv4 RPKI Invalids as seen by PREGINET.
• Current IPv6 RPKI Invalids as seen by PREGINET.

IPv6 Data

• Analysis Summary, basically the header of the daily e-mail.
• IPv6 Subnet Table, the number of subnets visible between /16 and /64.
• League Table of the number of IPv6 prefixes announced per ASN Globally. These are the ASes which are contributing most to the size of the Global IPv6 R&E Internet Routing Table.
• Bogon ASNs, the prefixes announced, and their paths.
• Dump of the Global R&E IPv6 table as seen by PREGINET.
• IPv6 prefixes and their origin ASNs
• IPv6 prefixes and their AS paths
• IPv6 announcements using deprecated AS_SET
• IPv6 MTR from the Collector to BGP feed source.
