Cloudflare Radar is Cloudflare's reporting website about internet trends and general traffic statistics. The website shows information about observed attacks and attack types and links to the DDoS report. General traffic statistics are reported, such as the used browser, fraction of human traffic, IP, HTTP, and TLS version.

The website also provides more detailed information on domains and IP addresses. Domains have information about age, popularity, and visitors. IP addresses have ASN and geolocation information.

• https://radar.cloudflare.com/ip/134.96.0.0

More information about Cloudflare Radar is available in the introduction blog post.

DMAP is a scalable web scanning suit which supports DNS, HTTPS, TLS, and SMTP. It works based on domain names and crawls the domain for all supported protocols. The advantage over other tools is the unified SQL data model with 166 features and the easy scalability over many crawling machines.

The DNS Census 2013 consists of about 2.5 billion DNS records collected in 2012/2013. The data is gathered from some available zone files and passive or active DNS collecting. The DNS records are written into CSV files containing one DNS record per line.

DNS Coffee collects and archives stats from DNS Zone files in order to provide insights into the growth and changes in DNS over time.

The website includes information such as the size of different zones. It tracks over 1200 zone files.

It provides searching through the zones files based on domain names, name servers, or IP addresses. It can also visualize the relationship between a domain, the parent zones and the name server in what they call a "Trust Tree".

The DNS Core Census is an ICANN project to gather information about top-level-domains (TLDs). This covers ccTLDs, gTLDs, effective TLDs (like co.uk), and entries in arpa. The census contains information about the zone, like metadata and contractual information, about the name servers, about addresses of the name servers, and the route origins. The data is kept for a 35-day rolling window.

Further information about the project can be found in this presentation and OCTO-019 from ICANN's Chief Technology Officer

This dataset contains the responses to DNS requests for all forward DNS names known by Rapid7's Project Sonar. Until early November 2017, all of these were for the 'ANY' record with a fallback A and AAAA request if necessary. After that, the ANY study represents only the responses to ANY requests, and dedicated studies were created for the A, AAAA, CNAME and TXT record lookups with appropriately named files.

The data is updated every month. Historic data can be downloaded after creating a free account.

• Having a route6 object in the RIPE Database
• Having a reverse DNS delegation set up

Contains a list of pricing information for different IXPs.

The website provides a tool to select a list of autonomous systems with a fairer probe distribution. Probes are not distributed equally, but rather cluster based on population. This leads to large biases towards western locations and certain autonomous systems. The website offers different distance metrics. The output is a list of autonomous system numbers for use in the RIPE Atlas API.

The mini internet project is part of the curriculum by the Networked Systems Group of ETH Zurich. It teaches the students the basic steps of how to create a mini internet. It starts with the basics of intra-network routing, by setting up multiple L2 switches. Then the students have to configure L3 routers to connect multiple L2 sites together. Lastly, in a big hackathon style, the students need to connect their local network with the network of the other students, by properly configuring BGP routers and setting up routing policies.

The code and the tasks are all available in the GitHub repository.

The APNIC Blog has a nice introduction to the project too.

Multi-level MDA-Lite Paris Traceroute is a traceroute tool, which understands and learns more complex network topologies. Often times, the network is not just a line, but multiple paths are possible and chosen at random.

A good description of the tool can be found in the RIPE Labs post or in the IMC 2018 paper.

Open INTEL is an active DNS database. It gathers information from public zone files, domain lists (Alexa, Umbrella), and reverse DNS entries. Once every 24 hours, data is collected about a bunch of DNS RRsets (SOA, NS, A, AAAA, MX, TXT, DNSKEY, DS, NSEC3, CAA, CDS, CDNSKEY). The data is openly available as AVRO files and dates back until 2016.

The data can be freely downloaded. There is documentation on the layout of the AVRO files.

The project is similar to Active DNS but seems to be larger in scope.

Open Traffic Generator (OTG) is an open standard, specifying a declarative and vendor neutral API for testing Layer 2-7 network devices and applications (at any scale).

PEERING is an environment where researchers and educators can play with BGP announcements in a real but sandboxed environment.

Description from the website:

The long-term goal of the PEERING system is to enable on-demand, safe, and controlled access to the Internet routing ecosystem for researchers and educators:

• PEERING for researchers. Today, it is hard for researchers to conduct Internet routing experiments. To perform a routing experiment, a research institution has to obtain Internet resources (IP addresses and ASNs) and establish relations with upstream networks. PEERING eliminates these obstacles and provides researchers controlled on-demand access to the routing ecosystem.
• PEERING for educators. Educators can use the PEERING infrastructure in teaching students the Internet routing architecture. The students access to live BGP sessions to multiple ISPs.

This is an improvement on the traditional traceroute program. It can detect multiple distinct routes and display them accordingly. The classical traceroute would produce weird results on changing network routes.

Another similar program is Dublin traceroute.

Passive DNS dataset from circl.lu.

Traceroutes can be difficult to understand. PathVis visualizes the network connections of your computer. It creates a tree of network nodes, with the root being the PathVis computer. The tree shows the paths to the other endpoints the computer is talking too.

The blog post introduces PathVis and explains the motivation behind it.

RIPE operates a set of probes, which can be used to send pings or similar measurements. The probes are mainly placed in Europe, but some are also in other continents.

All the collected measurements can be found in the RIPE Atlas Daily Archives. The blog post gives some more details.

The repository contains code for a better probe selection for the RIPE Atlas measurement system. Probes are not distributed equally, but rather cluster based on population. This leads to large biases towards western locations and certain autonomous systems. The goal of the repository is to find a more equal, thus fairer probe selection.

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.

The Route Origin Validation (ROV) Deployment Monitor measures how many AS have deployed ROV. It uses PEERING for BGP announcements and uses BGP monitors to see in which ASes the wrong announcements are filtered. A blog post at APNIC describes it in more detail.

The Shadowserver Scanning projects performs regular Internet wide scans for many protocols. The dashboard shows the gathered data about botnet sinkholes, Internet scans, honeypots, DDoS, and IoT data. This includes information about the size of botnets, the number of IP addresses with open ports like MySQL, the botnets as seen by honeypots, or the used protocols for DDoS attacks.

The blog post provides an introduction to the new dashboard.

The Shadowserver Scanning projects performs regular Internet wide scans for many protocols. They scan for four main types of protocols:

1. Amplification protocols, e.g., DNS or NTP
2. Botnet protocols, e.g., Gameover Zeus or Sality
3. Protocols that should not be exposed, e.g., Elasticsearch, LDAP, or RDP
4. Vulnerable Protocols, e.g., SSLv3

The website is a great resource to get general statistics about the protocols, like the number of hosts speaking the protocol, their geographic distribution, associated ASNs, and the historic information.
