Below is an open letter from our CTO, Marton Anka to our loyal Hamachi users.
Hi Hamachi users,
I’d like to announce a couple of changes to the LogMeIn Hamachi service that will take effect on the 19th of November.
The first change concerns the use of the 5.x.x.x address space. As you may or may not be aware, this address space has been allocated by IANA to RIPE NCC two years ago. RIPE NCC has been handing out these addresses to their customers, and having Hamachi active on your computer means that you’re not able to access a growing portion of the Internet. We’ve added IPv6 support to Hamachi a while back, and you can simply turn off the use of the 5/8 space, but we realize that IPv4 is still very important to most of you. Therefore we’ll be changing every Hamachi node’s address to the 25/8 space. The first octet of your Hamachi node’s IPv4 address will change from 5 to 25, the last three octets will be unaffected. If you’re using Hamachi with any sort of dynamic name resolution service (Bonjour, etc) you will not notice anything different. If, however, you use Hamachi IP addresses in scripts or, say, saved them in SSH client address books, you will need to change these and add the digit 2 in front.
Why 25/8? Well, it rhymes a bit with 5/8, and furthermore, it’s a block that’s been allocated to a foreign government agency for private use for almost two decades. We have no Hamachi users from this address space, and it’s highly unlikely that the general public would need to access one of these IP addresses. However, our general recommendation is that if you can, please turn off IPv4 support in your Hamachi clients. The IPv6 space we’re using has been registered to LogMeIn, and most modern software should function perfectly without needing an IPv4 address.
The second change concerns licensing. Hamachi is an extremely popular free service with many millions of active users, but we here at LogMeIn can only treat it as a hobby since the revenues from the paid product can only support a rather small dedicated development team after we pay for hosting, bandwidth and power. We have very interesting ideas for the Hamachi service’s future, but in order to fund development, we need more customers. We’ve introduced a very affordable pricing tier for Hamachi a while back; $29 per year gives you a network capable of hosting 32 computers. That’s less than a dime (or ten cents for you guys outside the US) per computer per month. You’re paying 250 times more just for electricity in any given month if you use your computer 8 hours a day.
So, in the hopes of converting more of you into paying customers, we’re making a small change to Hamachi: unless a computer is part of a paid network, you need to be logged in and running the Hamachi UI on your desktop in order to allow it to function. If no user is logged on to the computer then – even though the Hamachi service or daemon is active in the background – it will not go online in any networks that it may belong to. We believe this a fair change; if you’re using Hamachi casually (such as for gaming), then we’re glad to have you as a free user and this change does not affect you. If, on the other hand, you’re using Hamachi to access unattended computers, then this change does affect you and you will want to upgrade to the premium service in order to continue to benefit from it. If you upgrade to the premium service before the 19th of November you’ll save $10 on your standard subscription, that’s just $19/year for 32 computers. Like I said, the price couldn’t be more fair, and by upgrading, you’ll show your support to a few extremely bright and dedicated engineers as well as enable them to bring some extremely cool improvements to the product.
