All about Autonomous System

APNIC Labs Stats

Autonomous System | BGP | DNS | DNSSEC | Dataset | IP

APNIC gathers many statistics and offers them on their website. However, they provide way more data than it might initially look like, since many of the datasets are not linked from their main page.

BGPStream (OpenDNS)

Autonomous System | BGP | Dataset | Network

BGP Stream is a free resource for receiving alerts about hijacks, leaks, and outages in the Border Gateway Protocol.

BGP Steam provides real-time information about BGP events. It includes information about affected IPs, ASNs, and even a replay feature how the BGP announcements changed.

A live alert bot also exists on Twitter.

RIPEstat: Providing open data and insights for Internet resources

Autonomous System | BGP | DNS | Dataset | Network | Tool

RIPEstat is a network statistics platform by RIPE. The platform shows data for IP addresses, networks, ASNs, and DNS names. This includes information such as the registration information, abuse contacts, blocklist status, BGP information, geolocation lookups, or reverse DNS names. Additionally, the website links to many other useful tools, such as an address space hierarchy viewer, historical whois information, and routing consistency checks.

WAND Active Measurement Project

Autonomous System | DNS | Dataset | Network | Tool | Traceroute

AMP is a system designed to continuously perform active network measurements between a mesh of specialist monitor machines, as well as to other targets of interest. These measurements are used to provide both a view of long-term network performance as well as to detect notable network events when they happen.

The project is run with a custom client and server software. The measurement results can be viewed on the website. It includes traceroutes, latencies (DNS, HTTP, ICMP, TCP), HTTP page sizes, and packet loss. The software is available as open source.
