In practice, I think the “sign off” solution would work for very few people because of multiple devices in the network. My guess is that some very large percentage of OpenDNS users have multiple devices.

The TTL for releasing a customer IP address may be what they do today, again I’ve never seen the “stuck” problem.

Unless they use a fairly short TTL, I don’t see a solution to the problem of applying the wrong OpenDNS settings to a users network (in the dynamic IP case) given the nature of the DNS protocol.

However, in cases where a router is configured, I think OpenDNS should consider the “network” offline based on a certain time delay since the last transaction. I believe it is called TTL, based on how long my IP address is maintained by dynamic dns servers online. This can be very tricky, though.

The next question is… how long before OpenDNS queries the domain name to see if the same IP Address is still alive? Or, does it rely on the same TTL given by the dynamic dns providers? If so, that will make it automatic. In my experience, IP addresses gets stuck until OpenDNS detects IP Address change, sometimes via logging-in.

The next problem is when an IP address gets reused within the remaining seconds left on the TTL. Our ISP seem to have a very slow system in monitoring and changing this value. Sometimes, I have already turned off my computer for hours (sometimes for a whole day!), and still have the same IP address when I turn it back on, even during peak and non-peak Internet use. Since IP addresses can be spoofed intentionally, but not easily – without the ISPs support since conflict is bound to arise, I think OpenDNS can be fooled into believing that the same computer/network is still active when in fact it is no longer.

One way to resolve this is for the routers to be given by a secured key, that it will use in transacting with OpenDNS. If that number changes, then OpenDNS can safely say, “this must be another network”. This will require a re-write of all router codes out there.

Another way would be to have a change on how the DNS protocol operates. Including the mac-address of the host where the query originated. But since it does not, being a lightweight protocol, and for security issues involved… there you go.

My Horror. OpenDNS is stuck with a false (probably previous) IP address! No matter what I do, except the above, there’s just NO WAY for me to have OpenDNS re-scan my IP address! Boy, I felt so helpless! I feel like kicking the computer and the router altogether. hehehe. Glad I did not! haha.

Anyway, I feel like the solution for this matter is for the good team to have a button on the Network Settings page “permanently” placed. So if we ever get stuck with it, we will just have to ask OpenDNS to take a “second look” on our IP Address. Had this button been there permanently, my 3 hours of frustration would have been solved in 3 minutes or less.

My faith is NOT shaken! I will continue using your services… EVEN the extended ones!
Keep up the good work!

I think most companies assume that if they shout “green” loud enough, they’ll find the part of the market that cares about saving the planet, and that’s good enough. With even a little more care in their analysis, they could find the even larger market that also cares about saving money.

I wonder whether folks are considering the following… Could it be that “Windows” is just the kernel and the set of services/functionality that it provides, adjusted to the capabilities of the underlying hardware? The experience can then be adjusted, following a common UX theme based on Metro, according what can be done with the available screen estate, hardware, input devices, and so on. The huge benefit for developers and consumers would be the common platform. We standardize on the apps/tasks that we can perform, following a common UX theme, rather than on a set of windows and a chrome. I can access the same applications on my phone, laptop, desktop, TV, Xbox, and so on. Everything gets synced with the cloud. When I use “windows, I use the entire ecosystem. In my mind (again, this is a personal opinion), “Windows” represents the ecosystem that is being built to support my entire experience around apps/services.

I’d like to emphasize again that this represents my personal experience

The problem with the Skype VM seems to be on Skype’s side. There is no way to completely turn off voice mail there. It seems that Skype only forwards incoming calls if you are logged on, otherwise always goes to its own Voicemail. Some people have suggested that turning on the call screening (or call presentation) feature of GV solves the problem, but I don’t really want to screen my calls that way.

And I’m glad to see I’m not the only one with the Skype “where’s my voicemail?” problem. I was thinking I’d configured my Google Voice wrong.

Thanks for your blog

There are designer improvements, particularly that model changes shouldn’t get paved when refreshing the model. More major changes to help make the model more navigated are planned for the future (i.e., post .NET 4).

Inserts? Aside from some small performance improvements, nope. The woman I spoke to basically asked, “how’s that working out for you?” . . . she suggested that we bypass EF and use ADO.NET for the inserts instead.

I wasn’t able to find someone who knew the answer to the GUID / SEQUENTIALGUID questions I had. That doesn’t sound promising to me, but I’ll look further.

Any info on designer improvements, or bulk inserts?
