On this lovely Friday we have an Q-A with Tim Stoop. Tim is the Managing director for Kumina which is, as you can read in the first question, an company focused on support for infrastructure, administration and hardware.
Please tell us a little about Kumina
Kumina supports infrastructure for large websites and other internet-related services. We do Linux system administration, and partner with other companies who provide hardware and network support. Kumina currently has three employees, of which two are founders and equal owners.
We’ve designed and implemented solutions for several large websites which need highly available infrastructure. Our customers include several Dutch companies and some companies from other European countries (currently the UK, Sweden and Denmark), some of which have a 24×7 support contract and an availability guarantee.
When and how did IPv6 began to be a part of Kumina?
We’ve often toyed with it ourselves, but when we had to redesign our internal servers last year and our hosting providers both were starting their IPv6 tests, we decided we wanted to be completely IPv6 ready. As a result, our complete infrastructure is dual stack, supporting both IPv4 and IPv6. The one exception is our PBX, because Asterisk only has rudementary support for IPv6.
Customers that we host ourselves are also IPv6 ready, but none really use their capabilities. Self-hosted customers are very dependent on the infrastructure of their hoster, none of whom have an IPv6 deployment yet. We, however, can now say we have enough experience with it to feel comfortable deploying it at a customer’s site.
What is the current status of IPv6 at Kumina?
We’re fully IPv6 ready, except for our PBX.
In what way do you expect to see IPv6 growth in the next couple of years for Kumina?
We expect more and more customers asking us to make their setups dual stack. IPv6 will become more and more prevalent, especially once the IPv4 address space is ‘full’. So in a few years time we expect all our customers to be dual stack.
Are there any things you would like to say about IPv6 in general?
It’s a bit of a shame that many of the larger providers are so slow in adopting it. If they had more support for it, I think IPv6 would be far more prevalent than it currently is. Essentially, it’s not that big a deal, mostly similar to IPv4 with a few additional hurdles.
Thanks Tim for your time and answers!
Yesterday IANA announced that they allocated 31/8 and 176/8 to RIPE NCC. LACNIC and APNIC will most likely allocate two blocks each soon. It looks like we only are going to have 9 usable block after this summer.
