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.
APNIC REx shows general information about IPv4 and IPv6 usage and delegations. It features on overview of all AS connections. This is the replacement of the earlier vizAS tool.
The website contains a list of hundreds of looking glasses for various autonomous systems. All looking glasses are publicly accessible.
The website analyses RIB and BGP UPDATE information to find routing leaks. They determine a leak with the valley-free assumption, namely, if two major networks appear in the same AS_PATH. The leaks are timestamped and the faulty AS is shown.
An open-source software framework for live and historical BGP data analysis, supporting scientific research, operational monitoring, and post-event analysis.
BGP streams are freely accessible and provided by Route View, RIPE, and BGPmon.
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.
Overview of datasets, monitors, and reports produced and organized by CAIDA. Also contains links to other datasets.
Historical dataset about IP to ASN mappings.
Historical dataset about IP to ASN mappings.
The Internet Society gathers data to show the general health and availability of the internet. They measure four categories: internet shutdowns, technology use, resilience, and concentration. Under internet shutdowns, they show which countries are performing what kind of disruption, e.g., regional or national. The technology sections lists basic statistics about HTTPS, IPv6, TLS, DNSSEC.
Contains information for some networks about peering information. This includes peering partners, transfer speeds, peering requirements and similar.
Documentation
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.
