An organization of hobbyists who run an alternative DNS network, also provides access to domains not administered by ICANN.
Free service that gives wildcard DNS for anybody for free. Including RFC-1918 IP's. Pretty cool how they did it. Software is an add-on for PowerDNS.
An OSINT collection utility which gathers information about domains. Hunts for subdomains, searches SHODAN for hits, grabs banners and headers, web UI. Don't know if there's an API yet.
Bot that can be joined to the Mastodon network. Listens for people to send DNS resolution requests to it, sends back the canonical replies.
A website that can extract many different sorts of information pertaining to IP addresses and networks, least of all querying several dozen blacklists to see if an address has been flagged as a spammer's.
A utility that digs through DNS domain records to find things that aren't obvious, such as subdomains, hostnames with more than one kind of record associated with them, and IP address range calculation. It even Google scrapes to gather intelligence.
Enter an IP address, get a four little words-compatible hostname. Does the reverse, also.
Somebody's implemented mDNS/multicast DNS/Bonjour/Avahi/Zeroconf in Java. The classes allow developers to give their applications the capability to announce themselves on the local network so that other systems can find them.
An opensource recursive DNS resolver that is also DNSSEC capable. Used for resolving DNS requests rather than serving authoritative DNS zones. Modular architecture. IPv6 compliant. Cross-platform: runs on Linux, all of the BSDs, and Windows.
How to configure dnsmasq to return the same IP address for any A record a client might request. This feature was added for people constructing public access points.
How to configure dnsmasq to return the same IP address for any A record a client might request. This feature was added for people constructing public access points. The difference between this one and the other one is that this one is how to do it from the command line and not the configuration file.
An open source ebook about DNS in general and BIND 9 in particular. If you want to know how DNS works in practice and how BIND acts under different circumstances, this is a good way to start without the trial by fire.
An online point-and-click interface for DNS debugging using Dig.
infosec hacking A utility written in python that monitors a wifi network to find the most active users and lets you mess with their connection. You can spy on them preferentially or inject arbitrary stuff into their web traffic. Can also be used as a jammer. ew Pretty heavy dependencies but nobody in their right mind would rewrite them stuff for a single utility. Supports credential harvesting and dns spoofing.
Free dynamic DNS service.
This Free DNS hosting service is provided to help people that don't want to lose time and money with providers not always reactive to DNS changes. We can provide you primary and secondary name server for free (but if you like this service, please contribute !) All zones hosted as primary or secondary on our main server - ns0.xname.org, are automatically replicated on our secondary servers, ns1.xname.org and ns2.xname.org. We recommend to always use the 3 together for better redundancy.
How to set up MX records for subdomains (subdomain.foobar.com) that are separate from the primary domain and are authoritative when you are a Dreamhost customer. In other words, this is how you set up your Dreamhost configs such that you can send e-mail to subdomain.foobar.com and have it go to a separate mail server or provider from that for foobar.com.
A project that is developing an authoritative-only DNS in Python. Has a plugin interface for extending the system in arbitrary ways. Uses flat text files for zone files (ala BIND).
