Signpost

Signpost is a Mac application that creates and publishes domain name records on the local network. Designed to avoid needing to remember numeric IP addresses, Signpost makes addressing your devices simple. Signpost lets you publish multicast Domain Name System (mDNS) records on your local network. This means you can stop using numeric addresses such as 192.168.1.253 and instead use router.local. With Signpost the signs you create and publish are not only visible on your Mac but also on all other Bonjour, mDNS, and ZeroConf aware devices on the network. You can run Signpost on a single Mac and see the domains on your iPhone, iPad, and other computers with no additional set up.

Signpost supports both IPv4 and IPv6. The type of record published is automatically selected depending on the sign's Device field. It also supports Internationalised Domain Names (IDN), including support for emoticons within domains. Signpost supports both AppleScript and Automator. Signs can be exported and imported as files. mDNS is known as Bonjour on macOS and iOS.
