[mat-wg] RIPE IPmap v1.1.0: reverse-dns engine

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.

As always, you can get started with the API with the IPmap docs at:

Note: this mail was sent to ipmap at ripe.net yesterday, but I'm aware that 
not many people have subscribed to that list (yet). If you're interested
