Back in February 2012 we wrote a blog post regarding IPv6. Nimbus had received an allocation of addresses and had all hardware was prepared.
IPv6 is intended to replace the traditional IPv4 address range as there is rapidly becoming more devices connected to the internet than there is addresses available in the IPv4 range. RIPE have published a page regarding IPv4 Exhaustion – highlighting the reason why we only allocate one IP address with each of our hosting packages and SSL’s.
The IPv4 range allows approximately 4.3 billion addresses in a structure similar to: 18.104.22.168. IPv6 expands the available address pool by using a hexadecimal structure – 2a00:d680:1::3 for example, to up the pool 340 undecillion, 282 decillion, 366 nonillion, 920 octillion, 938 septillion, 463 sextillion, 463 quintillion, 374 quadrillion, 607 trillion, 431 billion, 768 million, 211 thousand and 456 addresses! (Try saying that at speed!).
Roll forward a year and a bit and we’re still ahead of the game.
- Our network is set up and ready for IPv6 communications – all of our servers, routers and firewalls are IPv6 ready.
- Nimbushosting.co.uk uses both IPv4 and IPv6!
- Our name servers are already using IPv6 – replication between our three nameservers is being performed over IPv6 and they are already handling requests too.
- Our communications with Nominet for domain registrations is performed using IPv6 – we’re talking to the Nominet registry using IPv6.
- Plesk 11 already supports IPv6 – good news for all our customers – Plesk and Windows 2008 are already supporting IPv6 – CPanel will shortly be doing so too.
- Some clients have been allocated address to their servers and are already testing functionality.
We’re keeping a close eye on IPv6. One of the biggest hurdles is that your home router will need to be IPv6 compatible before you can access any sites/servers that are solely using it. At the moment, networking equipment has a relatively long life cycle and before a switchover can occur, the majority of homes/businesses/public networks will need new routers that are IPv6 compliant.
If you would like to start testing your sites functionality with IPv6 (and you have access to a compliant router) drop us a line and we’ll provision some addresses on your server – don’t worry – you can still use IPv4 in a ‘dual stacking’ arrangement.
