mdns - Simple mDNS client/server library in Golang

•    Go

---

Simple mDNS client/server library in Golang. mDNS or Multicast DNS can be used to discover services on the local network without the use of an authoritative DNS server. This enables peer-to-peer discovery. It is important to note that many networks restrict the use of multicasting, which prevents mDNS from functioning. Notably, multicast cannot be used in any sort of cloud, or shared infrastructure environment. However it works well in most office, home, or private infrastructure environments.

skydock - Service discovery via DNS for docker

•    Go

---

Docker supports DNS based service discovery now. You should use the Docker implementation instead of this project. Skydock was built at a time when Docker did not support DNS discovery or auto registration. I'll keep the repo up for past years and as reference for others but don't use it if you have a recent version of Docker.Skydock monitors docker events when containers start, stop, die, kill, etc and inserts records into a dynamic DNS server skydns. This allows standard DNS queries for services running inside docker containers. Because lets face it, if you have to modify your application code to work with other service discovery solutions you might as well just give up. DNS just works and it works well. Also you cannot be expected to modify application code that you don't own. Passing service urls via the cli or in static config files (nginx) will not be possible if your service discovery solution requires a client library just to fetch an IP.

wagl - :bee: DNS Service Discovery for Docker Swarm

•    Go

---

wagl runs inside your Docker Swarm cluster and provides DNS-based service discovery (using DNS A and SRV records) and simple load balancing by rotating the list of IP addresses in DNS records. other containers in the cluster will be able to reach this container using URL http://api.swarm. It is a minimalist solution, yet handles most of the basic DNS service discovery functionality well ––but we're open to pull requests.

HomePWN - HomePwn - Swiss Army Knife for Pentesting of IoT Devices

•    Python

---

HomePwn is a framework that provides features to audit and pentesting devices that company employees can use in their day-to-day work and inside the same working environment. It is designed to find devices in the home or office, take advantage of certain vulnerabilities to read or send data to those devices. With a strong library of modules you can use this tool to load new features and use them in a vast variety of devices. Discovery modules. These modules provide functionalities related to the discovery stage, regardless of the technology to be used. For example, it can be used to conduct WiFi scans via an adapter in monitor mode, perform discovery of BLE devices, Bluetooth Low-Energy, which other devices are nearby and view their connectivity status, etc. Also, It can be used to discover a home or office IoT services using protocols such as SSDP or Simple Service Discovery Protocol and MDNS or Multicast DNS.

SkyDNS - DNS service discovery for etcd

•    Go

---

SkyDNS is a distributed service for announcement and discovery of services built on top of etcd. It utilizes DNS queries to discover available services. This is done by leveraging SRV records in DNS, with special meaning given to subdomains, priorities and weights.

Zero configuration

•    

---

When you read zeroconf, read Bonjour and UPnP. Bonjour is an Apple protocol which does the same thing as UPnP : Service Discovery. This project is a FULL .NET implementation. With this implementation comes a partial object implementation of the DNS protocol.

CoreDNS - DNS server that chains plugins

•    Go

---

CoreDNS (written in Go) chains plugins. Each plugin performs a DNS function, such as Kubernetes service discovery, Prometheus metrics or rewriting queries. It is a Cloud Native Computing Foundation inception level project.

mesos-dns - DNS-based service discovery for Mesos.

•    Go

---

Mesos-DNS enables DNS based service discovery in Apache Mesos clusters. mesos-N tags mark the start of support for a specific Mesos version while maintaining backwards compatibility with the previous major version.

lexicon - Manipulate DNS records on various DNS providers in a standardized way.

•    Python

---

Manipulate DNS records on various DNS providers in a standardized/agnostic way. Lexicon provides a way to manipulate DNS records on multiple DNS providers in a standardized way. Lexicon has a CLI but it can also be used as a python library.

JmDNS

•    Java

---

JmDNS is a java implementation of the IETF draft RFP multicast extensions for DNS. This project contains the needed elements for service discovery and service registration. It is compatible with Apple\'s Rendezvous service.

containerdns - a full cache DNS for kubernetes

•    C

---

ContainerDNS is used as internal DNS server for k8s cluster, and use DNS library : https://github.com/miekg/dns. containerdns-kubeapi will monitor the services in k8s cluster,when the service is created and has been assigned with external ips, the user(docker)in cluster can access the service with the domain. When the domain has multiple ips, the containerdns will choose one actived for the user randomly, it seems like a load balancer. Also the containerdns offer "session persistence", that means we query one domain from one user ip, then the user access the domain later, the user will get the same service ip.

dnsjava - DNS implementation in Java

•    Java

---

dnsjava is an implementation of DNS in Java. It supports all defined record types (including the DNSSEC types), and unknown types. It can be used for queries, zone transfers, and dynamic updates. A cache is used to reduce the number of DNS queries sent. A simple tool for doing DNS lookups, a 'dig' clone and a dynamic update client are included, as well as a simple authoritative-only server.

dnsdock - DNS service discovery for Docker containers

•    Go

---

DNS server for automatic docker container discovery. Simplified version of crosbymichael/skydock. This project was initially created and maintained by tonistiigi.

tenta-dns - Recursive and authoritative DNS server in go, including DNSSEC and DNS-over-TLS

•    Go

---

Tenta DNS provides a DNS server suite comprising an authoritative DNS server, recursive DNS server, and NSnitch, which provides a DNS server capable of recording the IP address of requests made against it and then makes that IP available via a JSON API. Tenta DNS also provides lookups for Tor Node membership, DNS blacklist status and Geo data. Finally, Tenta DNS includes built-in BGP integration, offering single engine convenience for DNS anycasting. We welcome people to use our hosted versions of recursive resolver and NSnitch. Please see Usage, for details on how to set Tenta DNS as your default DNS resolver, or APIs, for NSnitch REST API information. Just want to use our hosted recursive resolver? We offer two options, using either OpenNIC root servers or the normal ICANN root servers.

external-dns - Configure external DNS servers (AWS Route53, Google CloudDNS and others) for Kubernetes Ingresses and Services

•    Go

---

ExternalDNS synchronizes exposed Kubernetes Services and Ingresses with DNS providers. Inspired by Kubernetes DNS, Kubernetes' cluster-internal DNS server, ExternalDNS makes Kubernetes resources discoverable via public DNS servers. Like KubeDNS, it retrieves a list of resources (Services, Ingresses, etc.) from the Kubernetes API to determine a desired list of DNS records. Unlike KubeDNS, however, it's not a DNS server itself, but merely configures other DNS providers accordingly—e.g. AWS Route 53 or Google Cloud DNS.
