VPNs Fail Critical Security Tests

A VPN is meant to ensure the privacy of your communications through strong encryption, but new tests suggest that the most popular VPN services have critical security flaws.

If You're Not On IPv6, It Could Cost You A Fortune

We’ve long known that the pool of IPv4 addresses was near exhaustion — and as Tim Chown explains, that now means you’ll soon pay dearly if you’re not ready to shift to IPv6.

Why IP Reservation Matters For Cloud

Cloud deployments typically rely on abstracting away as many details as possible. So why would you want to assign something to a very specific IP address?

IPv6: No-One Apart From Telcos Cares Much

One of the topics readers suggested I look into while at Cisco Live! this week was what was happening with the uptake of IPv6. The short answer? Not much.

Why Disabling IPv6 In Your System Image Is A Bad Idea

Despite its benefits take up of IPv6 has been slow, and many sysadmins disable it by default. That’s a bad idea, since there is no easy way to change the setting back automatically across multiple machines.

IPv6 Still Slow To Attract Support

We have had occasion in the past to lament the relatively low uptake of IPv6 to date, despite a growth in the number of connected devices. Analysis by Cisco suggests that this situation will improve somewhat in Australia, but even so less than half of all internet-connected devices worldwide will be IPv6-capable by 2017.

Is Your Workplace Using IPv6 Yet?

There was a lot of discussion during our World Of Servers coverage last week about whether IPv6 would ever fully replace IPv4. There hasn’t been much movement among service providers, but what’s happening in your workplace?

World Of Servers Week 1: What We Learned

Lifehacker’s World Of Servers project kicked off last week with a series of posts from LCA2013 in Canberra looking at systems administration, virtualisation and the future of networking. Here are the key lessons we learned.

Should IPv6 Have A Different Name?

A footnote to our earlier discussion on why IPv6 hasn’t been widely adopted: the numbering of the newer version is clearly designed to suggest that it’s an improved successor to IPv4. But is that name actually logical and helpful?

Why Hasn't Everyone Moved To IPv6?

We’ve known for decades that the available pool of IPv4 address was eventually going to dry up, but despite numerous warnings usage of its successor IPv6 is still minimal. Why haven’t we migrated yet? Geoff Huston, chief scientist for regional internet registry APNIC, suggests that the answer is that carriers are too cheap to make the switch and are happy to rely on network address translation (NAT) systems instead.
