Signposts automate the process of establishing and maintaining
routes across the modern Internet by exploiting DNS
as a ubiquitous signalling channel (§3). Every user registers
a unique domain name (e.g., alice.signpost.io) and binds
stable names to their devices as a one-off process (e.g., phone
and home). DNS responses for these domains are served by
authoritative Signpost servers running in the cloud and on
latency, as well as energy and financial costs [6, 2].
