Download of Signpost 1.0.1 for Mac was available from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X was originally created by Graham Miln. The application relates to Internet & Network Tools. We recommend checking the downloaded files with any free antivirus.
From the developer:
Signpost 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`.
