使い始めてすぐ、同じ8月の28日にDynDNSから届きました。無料のDDNSホスト名は2個までで、ドメイン名も18個に減りました。大抵のユーザーはホスト名を1個だけ使っていて、それだったら無料で2個までで充分でしょうという事で、それ以上欲しければ年間15ドルのDynDNS Proに移行して下さいということでした。その時点で、じゃあ予備の1個を確保しておこうともう1個登録して合計2個のDDNSホスト名を使ってきました。

subject:Changes to NEW DynDNS.com Accounts


As you may have seen, we are making some changes to Dynamic DNS accounts. Instead of making the changes without notice, we wanted to give all of our existing customers a heads up and explain why we are making these changes.

What changes are you talking about?

Previously we allowed each Dynamic DNS account to have 5 free hostnames and you could select them from 88 different domains that we own. Now this will be limited to 2 free hostnames from 18 DynDNS branded domains.

Also, we are increasing the number of hostnames that come with a DynDNS Pro upgrade. Previously, each DynDNS Pro upgrade gave you the ability to add 25 additional hostnames. We are increasing that number to 30.

Why are you making these changes?

There are a number of reasons that we thought it was important to make these changes now.

  1. Having 88 free domains to choose from was overwhelming for many of our new users. By reducing this to 18 it makes it easier for people to get started.
  2. By limiting the free options to the DynDNS branded domains, it helps grow the awareness of our services. Although we are happy to offer our free services, we simply ask that you help spread the word to other people who might find our paid services helpful. We have to pay those bills somehow.
  3. Looking at the stats of our users over the past 12 years, we see that the vast majority of people only use 1 free hostname. Our support team has seen a lot of confusion caused by the five free hostnames, so when you combine that with the normal use case, it just made sense. We are allowing the 2nd hostname for those who need to create a WebHop to access your hostname. If you are going to need more than 1 or 2 hostnames there’s a good chance you are using us for something important. If that’s the case, we simply ask that you pay $15/yr for the DynDNS Pro upgrade, which provides a number of other benefits.
  4. If you are using our services for business critical needs, you should consider our Custom DNS service.

What will happen to my current account and hostnames?

Nothing, as long as you keep your hostnames active and up-to-date. If you allow your account or hostnames to expire, you will have to select from the new domains instead and will be limited to the 2 free hostnames. To ensure you aren’t affected by these changes, upgrade to DynDNS Pro for just $15/yr. Again, there are a number of other benefits to upgrading.

You’re just trying to force us to pay you, aren’t you?

No, not really. As long as you keep your account active, you won’t be affected by these changes. We would never want to have a user feel like they were forced to use our services. This does not seem to be a very good business model to us. You do your part (log into your account or update your hostname monthly) and we will do ours (continue to offer free Dynamic DNS services to you).

結果的に他の動的IPの場所に別のサーバーを置いたりで2個とも活用できててよかったのですが、今年の5月28日に、こんなメールが届きました。DynDNSはDyn Inc.に変わってます。個人アカウントの情報部分は加工してます。

Subject:Your free Dyn hostname will expire in 5 days

Dear Dyn Customer,

Your Dyn account “xxxxxxxx”, free hostname(s) will expire in 5 days. If you no longer need the hostname(s), simply disregard this email and allow expiration to occur.

Free hostnames must be updated every 30 days to remain active. Inactive hostnames will expire and be deleted. If you wish to prevent the hostname(s) from expiring, please visit the link below: https://account.dyn.com/eml/expatconf/?/?????????????

Keep your hostname(s) active without having to update every 30 days, by purchasing a DynDNS Pro upgrade today.

Thanks for choosing Dyn.

Please do not reply to this email. If you have additional questions please visit Dyn Support.

今まではDDNSホスト名をアクティブ(要するに適宜IPアップデートして使っていればいい)にしていればよかったのが、今度は30日という日数制限を始めました。それが面倒ならDynDNS Proにアップグレード(有料)に移行してくださいということだそうです。

Subject:Dyn Account SLA Update
If you would like to maintain your free Dyn account, you must log into your account once a month. Note that using an update client will no longer suffice for this monthly login. You will still continue to get email alerts every 30 days if your email address is current. Failure to login once per month will result in expiration and loss of your hostname.

We understand that the possibility of resulting service interruptions may be frustrating, so we are offering an upgrade offer to VIP status (Dyn Pro) for just $10 USD for the first year. Under this status, monthly login is not required and service will remain uninterrupted.

Here’s how you get this done in two easy steps:
1) Login to account.dyn.com.
2) Click here to add the Pro service to your cart at the $10 VIP rate. The discount will be applied upon checkout.

今度はDDNSのクライアントによるアップデートだけでは駄目で、最低30日ごとに1回はDyn Inc.のアカウントログインが必須になりました。元々、DDNSのサービスは一度設定してしまえば大抵の場合は何もすること無しに使い続けるものです。約1ヶ月に1回は大したことはなさそうに見えても普段意識しないで使っているサービスのことを毎月思い出してログインするのは結構大変です。これに対して例えばDYNDNS Auto Login – A programmatic approachとかDyn SLA Update – or, How To Lose Friends and Alienate Customersとか、自動的に毎月ログインする仕組みを作ったという方も見受けられます。何か力の入れる方向が間違っている気もしますが、そういうことでもしないと忘れたりして面倒だということですよね。


で、今後どうするか?ですが、こういった無料のDDNSサービスは他にも結構たくさんあるのでそれを使うのも手です。「無料DDNS」とか「Free DDNS」とかでぐぐればすぐに見つかります。ただ、どこも無料が故にサービスの継続性について確かなことは言えない雰囲気が感じられます。それでも焼畑農業のように次々と無料サービスを渡り歩く気ならいいのですが、私の場合、なかなか設定に行けない場所にあるDDNSクライアントをDDNSサービスが変わる毎に変更するのも面倒、というかそれ以前に設定する機会がなかなか無いというリスクもあります。
