Dear colleagues,
In November of last year, we released version 1.0.0 of RIPE IPmap. The
main feature of that version was the new latency engine, but we also
included a prototype of the “reverse-dns” engine, which used very basic
pattern matching of hostnames from PTR to provide location guesses.
We are pleased to announce that with v1.1.0 the reverse-dns engine has
received a major upgrade, allowing it to provide much better geolocation
answers through pattern analysis of the entire IPmap “latency” and
“worlds” datasets, with daily analysis performed mostly thanks to the
sc_hoiho tool from CAIDA’s scamper toolkit.
More information about the new engine, as well as links to information
on the sc_hoiho tool and its theoretical underpinnings can be found at:
https://ipmap.ripe.net/docs/01.manual/#reverse-dns
As well as the new and improved reverse-dns engine, the suggestion
system has been improved to better combine results from the various
geolocation engines, and the "single-radius" engine has been more
closely integrated into the "latency" engine, with both offering basic
anycast detection.
As always, you can get started with the API with the IPmap docs at:

Kind regards,
