IPv4 IP country address block aggregation

August 15th, 2014 3 comments

Starting from August 15th, 2014 you can download our aggregated country IPv4 address blocks. By aggregating multiple smaller blocks into larger IP prefixes you can increase your firewall, packet filter or router performance. Why? You will have less firewall rules – each incoming or outgoing IP packet will be inspected faster, probably will use less memory, use less network buffers and CPU (or ASIC?) load will decrease.

IP address block aggregation really works for zone files that have IP address blocks allocated without gaps. For example, USA total IP block allocations are around 46000 and we can aggregate those blocks down to about 15400 IP prefixes), Australia (~6500 vs ~4300 aggregated), Canada (~6900 vs ~3600 aggregated), China, France, Germany and many other countries….

I hope you will enjoy aggregated IPv4 block downloads from Don’t hesitate to give us some thumbs up ๐Ÿ˜‰

Quick update on country IP block generation ( August 10th, 2014)

August 10th, 2014 No comments

Sorry guys, I had to move to another country so I was a bit lazy to fix the scripts. I have updated and fixed all the required scripts. From now on IP blocks will be updated — once a day at ~12:05 UTC time.

Soon, I will also implement additional features/services and looking forward to offer ASN and IPv6 record blocks downloads, free of charge as usual. Stay tunned!

Temporally problems with APNIC IP allocations

September 30th, 2012 7 comments

Hey guys…we received a report that we are missing some IP ranges from APNIC allocations, especially from the New Zealand (NZ) . We will check this out and see why we are missing those ranges as we automatically parse APNIC official database files. Anyway, thanks for the report and your feedback Dave W. – we will definitely sort this problem out shortly!
