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.

Cloudflare Radar is Cloudflares 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.
More information about Cloudflare Radar is available in the introduction blogpost.
The Radar data is also available via API, for example the attack data: https://developers.cloudflare.com/api/operations/radar_get_AttacksLayer3Summary

https://dnscensus2013.neocities.org/
DNS | Dataset | IP | NetworkThe 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".
https://observatory.research.icann.org/dns-core-census
DNS | Dataset | IP | NetworkThe 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 ICANNs Chief Technology Officer

https://github.com/akamai/entropy-ip
IP | IPv6 | ToolThe Entropy/IP algorithm allows for inspecting and generating IPv6 addresses. Entropy/IP can determine the entropy of different nibbles and the relationship between different components. Based on this analysis, it can also create valid-looking IPv6 addresses.
https://github.com/DNS-OARC/flamethrower
DNS | IP | Network | ToolFlamethrower is a small, fast, configurable tool for functional testing, benchmarking, and stress testing DNS servers and networks. It supports IPv4, IPv6, UDP, TCP, DoT, and DoH and has a modular system for generating queries used in the tests.
https://opendata.rapid7.com/sonar.fdns_v2/
DNS | Dataset | IP | NetworkThis 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.
Some Open DNS operators provide a way to return the IP address of the request packet.
Google DNS:
dig o-o.myaddr.l.google.com txt @ns1.google.com +short
OpenDNS:
dig myip.opendns.com @resolver1.opendns.com +short
Akamai:
$ dig +short TXT whoami.ds.akahelp.net
"ns" "2001:db8::abcd"
"ecs" "203.0.113.0/24/0"
"ip" "203.0.113.132"
The ds stands for dual stack. It is also reachable under whoami.ipv6.akahelp.net to force IPv6 or whoami.ipv4.akahelp.net to force IPv4.
ns stands for the unicast IP address of the recursive resolver. ecs contains the EDNS client subnet information if the resolver uses the option. In this case, ip contains a representative IP within the ECS, not necessarily the IP of the client.
The new version is introduced in this blog post https://www.akamai.com/blog/developers/introducing-new-whoami-tool-dns-resolver-information.
The old version might be decommissioned:
dig whoami.akamai.net. @ns1-1.akamaitech.net. +short

https://github.com/measurement-factory/ipv4-heatmap
IP | ToolThe IPv4 heatmap tool draws an image of active IPv4 addresses. The IP addresses are mapped to pixels using a Hilbert curve or a Z-curve. The image can be extended with annotations about the address space, for example, to show which regional internet registry is assigned to the address.

A curated list of IPv6 hosts, gathered by crawling different lists. Includes:
Access to the full list requires registration by email.
Based on the paper "Scanning the IPv6 Internet: Towards a Comprehensive Hitlist".
The website contains the additional material of the IMC paper Clusters in the Expanse: Understanding and Unbiasing IPv6 Hitlists. The IPv6 addresses can be downloaded from the website. The website has three lists, responsive IPv6 addresses, aliased prefixes, and non-aliased prefixes. Additionally, the website also has a list of tools used during the data creation.
These projects either operate DNS based Real-time Blackhole Lists (RBL) or allow checking if an IP is contained. The Multi-RBL websites are helpful in finding a large quantity of RBLs.
https://github.com/nsg-ethz/mini_internet_project
BGP | IP | Network | ToolThe mini internet project is part of the curriculum by the Networked Systems Group of ETH Zurich. It teaches the students the basic steps 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.
https://gitlab.planet-lab.eu/cartography/
IP | Network | ToolMulti-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 avaible 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.
This is an improvement on the traditional traceroute program. It is able to 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.

IP | Network | ToolTraceroutes can be hard 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.
Shodan performs regular scan on common ports.
Access is free, but requires registration. More results can be gained with a paid account.

It's goal is to identify router interfaces and interconnections on internet scale. Conceptually this is similar to running many traceroutes and stiching them together into one view. However, traceroutes are designed to understand the connection between two hosts and do not scale easily.
Different utilities for network scanning. Most imporantly the zmap component, which is a packet scanner for different protocols. It also contains other tools like ways to iterate over the IPv4 address space and blacklist/whitelist management.
dn42 is a big dynamic VPN. It employs various Internet technologies, such as BGP, whois, DNS, etc.

Mostly different hackerspaces participate in the dn42 network, such as different locations of the CCC.
