512K Day; the day the global Internet broke under its own weight.

Posted by Dan Pope on Sep 1, 2014 2:36:29 PM

Tuesday 12th August, 2014, has been marked as “512KDay”, the day the global Internet broke under its own weight. The Internet has been growing at a vast rate and 512K routes have always been noted as a significant number of routes on the routing table. On Tuesday 12th August, 2014, the 512K mark was passed.

Why 512K? 512K (or to be exact 524,288 or 2-to-the-19th power), is the maximum number of routes supported by the default TCAM configuration on certain aging hardware platforms. TCAM (Tertiary Content Addressable Memory) is where the routing tables are stored. On the 12th as the total number of routes passed 512K, the devices could not hold all of the necessary routes in memory and thus crashed.

Moving onto IPv6

Posted by Dan Pope on Apr 11, 2014 11:26:38 AM

Time is almost upon us for the addressing system of the Internet to almost be completely used up. I believe I have been saying this for the last 5 years, but it looks like in the next 12-24 months people are going to be brought to a halt. Thankfully most ISP’s have got more than enough IP ranges to cover us for the foreseeable future, as well as ready to start with the new system in the guise of IPv6.

RIPE soon to be issuing from the last ever IPv4 block

Posted by Dan Pope on Sep 6, 2012 9:29:51 AM

Fluidata received notice from RIPE on Tuesday that they now have just a /10 left before their last /8 of IPv4 addresses. What this means is, that at current allocation levels, there is about 1 months’ worth of IPv4 space left across Europe before RIPE have to start issuing from their last ever block.
