dn42 can be used to learn networking and to connect private networks, such as hackerspaces or community networks. But above all, experimenting with routing in dn42 is fun!

Online tool for Whois lookups

The Network Situational Awareness (NetSA) group at CERT has developed and maintains a suite of open source tools for monitoring large-scale networks using flow data. These tools have grown out of the work of the AirCERT project, the SiLK project and the effort to integrate this work into a unified, standards-compliant flow collection and analysis platform.

If you are new to the NetSA Security Suite, start with this overview of the components that comprise the NetSA Security Suite and their inter-operation.

CERT is a part of the Software Engineering Institute (SEI), a federally funded research and development center (FFRDC) operated by Carnegie Mellon University.

Features:

• ipv4 allocation table
• some registration data of all assigned and allocated blocks
• AS information and announced own prefixes
• geolocation data for ipv4 addresses
• all domains for ip address

Limitations:

• 500 requests from registered users within 24 hours.
• 200 requests from one ip address within 24 hours for unregistered users.

Data sources:

• registered blocks: regional registers: RIPE NCC, ARIN, APNIC, LACNIC, AFRINIC
• BGP table: Route Views Project
• Geolocation data: NetLoad, MAXMIND, IpGeoBase.ru, local additions. This site or product includes IP2Location LITE data available from http://lite.ip2location.com.
• Icons: Fugue Icons
• Flags: flags.blogpotato.de and Maxmind
• Social icons: komodomedia

The goal of the Glasnost project is to make ISPs' traffic shaping policies transparent to their customers.

NAT64Check is a tool developed by the Internet Society in collaboration with Stichting IPv6 Nederland, Go6, SJM Steffann, Internetbureau Max and Simply Understand. This allows you to enter the URL of a particular website, and then run tests over IPv4, IPv6 and NAT64 in order to check whether the website is actually reachable in each case, whether identical web pages are returned, and whether all the resources such as images, stylesheets and scripts load correctly. It also compares responsiveness using the different protocols, therefore allowing network and system administrators to easily identify anything is ‘broken’, to pinpoint where any non-IPv6 compatible elements need to be fixed.

We're the first company in Hackers & Founders startup accelerator and we love solving cross-browser testing problems!

Robtex uses various sources to gather public information about IP numbers, domain names, host names, Autonomous systems, routes etc. It then indexes the data in a big database and provide free access to the data.

We aim to make the fastest and most comprehensive free DNS lookup tool on the Internet.

Our database now contains billions of documents of internet data collected over more than a decade.

Nous partageons les données qui révèlent comment les règles et les actions des autorités administratives et des entreprises affectent la confidentialité, la sécurité et l'accès aux informations.

Je n'ai rien à cacher. En fait si, et vous également !

FreeboxOS Gateway APi allow access to Freebox Server settings and apps.

This API can be used to develop companion apps for Smartphone, or provide an alternative to FreeboxOS web app.

It is a complicated, arduous, and time-consuming task for even experienced system administrators to know what a reasonable set of security settings is for any operating system. Thus, the FIRST Best Practice Guide Library intends to assist FIRST Team Members and public in general in configuring their systems securely by providing configuration templates and security guidelines.

Also, this initiative aims at recognizing FIRST members' work and promote it outside the FIRST community.

For many years, DomainTools has served the domain professional community with Whois and domain name research tools to drive your investments, research buyers, find new domains and manage existing portfolios.

I-Blocklist is a service dedicated to the distribution of Internet Protocol address lists.

How does it work?
I-Blocklist distributes lists in standard formats including P2P, DAT, and CIDR.
Our lists can be used with software such as PeerBlock, PeerGuardian, iplist, Vuze, Transmission, uTorrent and, pfBlocker.

Like telephone numbers there are directories that relate the IP addresses to names such as "cnn.com". These names are called domain names and the directories are run on servers called Domain Name Servers or DNS. A Reverse DNS Lookup queries these servers in an attempt to find a match.
