New to Smart Network Data Services? Getting started is easy! Proceed to our
page, enter an IP range or ASN that you own, and just a few clicks later you'll see a wealth of information on those IPs' mail, spam, virus and other statistics.
The momentum continues!
Going strong for well over 3 years now, we're proud that SNDS is now used by over 20,000 organizations to provide transparency over 200 million IPs! And to accelerate this great progress, we're excited to release even more improvements. We're introducing a new page where you can see the current status of your IPs, if they're
! We've also done some performance and reliability enhancements, to keep up with the ever-growing size of the system. Our hope is these changes will make SNDS even more useful and compelling for people to manage their outbound traffic and network higene.
We're pleased to announce a major upgrade to SNDS! After reading and carefully considering all the great
we received, we looked at the scenarios most important to enable and streamline and are excited to reveal the results. We've done everything from tweaks under the hood, to adding the ability to
sign up by Autonomous System Number (ASN)
, to expanding the types of data we provide from just mail and spam to include viruses and malware, to
making all that data accessible to automated processes
All this is in the hopes of better serving SNDS' ever-growing community. And as always, we look forward to
on how this new version is being used and how it could be improved. To date, we have many thousands of users now covering over 87 million IPs. The more users, the more IPs, the more good that SNDS does--so
tell your friends
Great initial success!
Weeks after our official announcement, hundreds of organizations have been able to sign up for Smart Network Data Services and start reviewing data with it. In fact, the data on IP space covering over 50 million IPs has been provided to their owners!
We've also received lots of very positive, constructive, and useful
. While we can't promise a response to every one, we do read and consider them all very carefully and appreciate each of them. We look to continue improving this service in the future, as time allows, and feedback from the community and industry are key to our efforts. Feedback describing how SNDS is used, particularly when stopping spam, will always be especially rewarding and useful.
