Historic datasets (from 2014 onwards) for the .nl TLD. Datasets are available in JSON format.

Datasets | DNS | Networks
Historical DNS database. Access can be requested for academic use.
Activly queries many DNS records, e.g., .com zone.
It can contain information not in DNSDB, if the information was never seen by a resolver.
It does not contain all informatin, as some domains may be unknown to the project and thus cannot be crawled.
It uses popular zones, domain lists (e.g., Alexa, blacklists) and other domain feeds.
They normally maintain a rolling 14-day window.
Copy files (for date 2017-10-05) (ddos@gladbeck):
sftp -B1024000 -C -rp "activedns@kokino.gtisc.gatech.edu:active-dns/20171005/" .
The data is encocded in AVRO format, which can also be parsed as JSONL. Python has a AVRO library. AVRO schema:
{
"namespace": "astrolavos.avro",
"type": "record",
"name": "ActiveDns",
"fields": [
{"name": "date", "type": "string"},
{"name": "qname", "type": "string"},
{"name": "qtype", "type": "int"},
{"name": "rdata", "type": ["string", "null"]},
{"name": "ttl", "type": ["int", "null"]},
{"name": "authority_ips", "type": "string"},
{"name": "count", "type": "long"},
{"name": "hours", "type": "int"},
{"name": "source", "type": "string"},
{"name": "sensor", "type": "string"}
]
}
Some more information about some fields that are unique to that schema. The IPs in Authority IP are the collection of the authority name server IPs that replied to our query. We gather all the IPs that gave us the same answer for an entire day and concatenate them on the same field, mostly in order to reduce the number of records that we have to keep. The only field that might be slightly confusing, is the "hours" field. This is a 24bit integer that encodes the time of day we saw this RR for date date (for example, 000000000000000001000010 = 18:00 and 23:00). Another important thing to keep in mind, is NXDOMAINs. A resolved QNAME does not exist when both the rdata and ttl fields are equal to null. If rdata exists but ttl is null then the record was part of the glue of the DNS packet and not in the answer section.
A similar active DNS project is Open INTEL which seems to be larger in scope and the data is publicly available.

Akamai provides aggregated data about the root servers. They provide the overall amount of DNS queries, trends, and IPv4/IPv6 query ratios.
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 for domains and IP addresses. Domains have information about age, popularity, and visitors. IP addresses have ASN and geolocation information.
More information about Cloudflare Radar are available in the introduction blogpost.

Datasets | DNS | Networks
The DNS Census 2013 consist 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 track 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://opendata.rapid7.com/sonar.fdns_v2/
Datasets | DNS | Networks
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 neccessary. 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.

The IPv4 heatmap tool draws an image of active IPv4 addresses. The IP addresses are mapped to pixels useing 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.
Per continent, region, or country measurements of IPv6 deployment and preference. Allows to access historical data.

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.

BGP | Networks | Tools
The mini internet project is part of the curiculum 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.

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 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.

Yarrp is a active network topology discovery tool. 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.
https://github.com/zesplot/zesplot
Tools
zesplot is an IPv6 visualization tool. It turns a list of IP addresses into a picture, for example as a heatmap representation. It works based on squarified treemaps, since the IPv4 way of space filling curves works poorly for such a sparse space.
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.
