Discover and Query Multicast DNS (mDNS)/zeroconf Services

Description

Multicast DNS (mDNS) provides the ability to perform DNS-like operations on the local link in the absence of any conventional Unicast DNS server. Given a type of service that a client is looking for, and a domain in which the client is looking for that service, this mechanism allows clients to discover a list of named instances of that desired service, using standard DNS queries. This mechanism is referred to as DNS-based Service Discovery, or DNS-SD. Tools are provided to perform service discovery and query for specific services over multicast DNS (mDNS).

What’s Inside The Tin

The following functions are implemented:

• bnjr_discover: Browse available services
• bnjr_query: Look for a particular service

Installation

install.packages("bonjour", repos = c("https://cinc.rud.is", "https://cloud.r-project.org/"))
# or
remotes::install_git("https://git.rud.is/hrbrmstr/bonjour.git")
# or
remotes::install_git("https://git.sr.ht/~hrbrmstr/bonjour")
# or
remotes::install_gitlab("hrbrmstr/bonjour")
# or
remotes::install_bitbucket("hrbrmstr/bonjour")
# or
remotes::install_github("hrbrmstr/bonjour")

NOTE: To use the ‘remotes’ install options you will need to have the {remotes} package installed.
