APNIC Labs Stats

 https://stats.labs.apnic.net/

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.




Censys

 https://censys.io/

Certificate | DNS | Dataset | IP | Network

Censys performs regular scans for common protocols (e.g., DNS, HTTP(S), SSH). Provides a search for TLS certificates.

Access is free, but requires registration. The website no longer provides free bulk access. Bulk access requires a commercial or a research license. The free access is limited to 1000 API calls per day.

Cloudflare Radar

 https://radar.cloudflare.com/

DDoS | Dataset | IP | Network

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.





DNS Coffee

 https://dns.coffee/

DNS | Dataset | IP | Network | Search

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".





Entropy/IP

 https://github.com/akamai/entropy-ip

IP | IPv6 | Tool

The Entropy/IP algorithm allows for inspecting and generating IPv6 addresses. Entropy/IP can determine the entropy of different nibbles and relationship between different components. Based on this analysis it can also create valid-looking IPv6 addresses.



Forward DNS Rapid7

 https://opendata.rapid7.com/sonar.fdns_v2/

DNS | Dataset | IP | Network

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.


Get your public IP using DNS

 https://docs.google.com/spreadsheets/d/1lkNJ0uQwbeC1ZTRrxdtuPLCIl7mlUreoKfSIgajnSyY/htmlview

DNS | IP

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 option is used by the resolver. 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 decomissioned:

dig whoami.akamai.net. @ns1-1.akamaitech.net. +short

IPv4 Heatmap

 https://github.com/measurement-factory/ipv4-heatmap

IP | Tool

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.



IPv6 Hitlist Collection

Dataset | IP | Network

https://www.net.in.tum.de/projects/gino/ipv6-hitlist.html

A curated list of IPv6 hosts, gathered by crawling different lists. Includes:

  • Alexa domains
  • Cisco Umbrella
  • CAIDA DNS names
  • Rapis7 DNS ANY and rDNS
  • Various zone files

Access to the full list requires registration by email.

Based on the paper "Scanning the IPv6 Internet: Towards a Comprehensive Hitlist".

https://ipv6hitlist.github.io/

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.



Lists of DNS Blacklists

DNS | Dataset | IP | Network | Spam | Tool

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.


Mini Internet Project

 https://github.com/nsg-ethz/mini_internet_project

BGP | IP | Network | Tool

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.



Open INTEL

 https://www.openintel.nl/

DNS | Dataset | IP | Network

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.

 https://dn42.eu/Home

BGP | IP | Network | VPN

dn42 is a big dynamic VPN. It employs various Internet technologies, such as BGP, whois, DNS, etc.

Users can experiment with technology, they normally would not use in a separated environment.

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