Is 1.1.1.1 still the fastest DNS?

Is 8.8 8.8 safe?

I'm interested in purchasing a used 8.

8mm, 40gn lens and would like some feedback as I've never had the lens out before. While I do not wish to shoot with it, I do wish to test it so as to assure myself it is safe for my system to use. If someone has used the lens for shooting purposes, I'd like to know what they found about its safety. (Thanks)

If you have a digital camera, then just take a shot of the "marker" printed on the barrel, next time you put the lens on that barrel will be there. It should be easy to see, if there is a mark.

It was the first thought that popped into my head as well, that's why I was asking for feedback. The next time it is time to put the lens on I'll also notice if anything else changes. So as not to get lost in questions of whether a manufacturer calls it safe or not, safe-ness, is subjective isn't it? What I'd like to find out more about is whether there is a risk of the glass coming off, or becoming misshapen from the vibration, if the lens is left out and exposed to the elements in a garage or garage-like area. (Again, it's hard to know without the lens in your hand)

It's safe to use them as long as the lens itself isn't cracked. It's also safe to use them at close focus distances. If the front element becomes dislodged from the body it will shatter and break. That said, it's not the safest way to use a fixed F/22 lens but if you are careful, it's an OK way to use it. I have a few 8.8/40's that were dropped when I was young. One of them has never been dropped again. I am going to get a 16.5 mm f/3.5 and hope the weight difference keeps it from being dropped too much.

As far as vibration, it depends on the quality of the product.

Is 1.1.1.1 still the fastest DNS?

I have been following this topic for some time now, and finally decided to post a quick summary of my findings.

The main advantage of a DNS server that makes it worth running is that it is a single-purpose box that can do everything DNS needs. This means it does not have to be powerful and can be extremely light weight. Because it only runs DNS, it does not need any other services like web or mail servers.

What I want to do is to run my own DNS server for the family (with no spam and no ads) and compare its performance to BIND, PowerDNS, and Bind with Zones. I chose these two because they are the two most popular options.

I had already tested PowerDNS and found it to be good enough to replace the PowerDNS that I was running on my home network. But I wanted to test it against the DNS server that is in the cloud, so I could compare the two. I am using these benchmarks:

My results show that DNS over UDP is slower than DNS over TCP for small queries (up to 16 queries). With more queries, DNS over UDP starts to outrun DNS over TCP.

The PowerDNS instance I tested was using 32GB RAM and a 32-core Intel(R) Xeon(R) CPU X5355 @ 2.93GHz with the latest updates. My server has a similar configuration, but with 48GB RAM and 4 x 8-core Intel(R) Xeon(R) CPU X5335 @ 3.33GHz. The difference is that PowerDNS uses a lot of memory for caching. I noticed that it was using over 1GB of RAM.

My DNS server is running on a 64-bit CentOS 5.4 server, with two 2.8GHz quad-core AMD Opteron(tm) processors. I have set the memory to 4GB of RAM.

I ran the tests with a minimum of 20 queries, and compared the results. When I was testing the new features that came with PowerDNS 4.3, I also tested the new features that came with DNS over TCP. I also looked at the PowerDNS DNS over TCP plugin.

I tested the new features of PowerDNS that came with PowerDNS 4.3, namely DNS over UDP and DNS over TCP.

Why should I use it?

You should use WebDAV protocol because if you're on a Windows server it makes administration of the files on your computer easier. You just upload the file(s) directly from your local machine to a WebDAV server.

You are connected to any Windows PC, Mac or Linux via the internet and you want to store some web content that you can access from a web browser. On your PC desktop you've just created a new folder called WebDAVServer but that folder needs to have some special properties if you want your content stored in this folder accessible by some online server. On your Windows PC desktop right click in the New Folder and select Properties. You want to change 2 things: 1) Change the Type to something more descriptive. The default is WebDAV Server. I usually change it to something that includes the WebDAV prefix so I know that it is a WebDAV folder: WebDAV Share.

2) Change the location of the server. I keep the folder name in my Documents directory so that I can easily access it from both Windows and macOS systems. Once you've set these properties, make sure to click OK. You can now upload files directly to that folder from any location via a web browser.

The good thing about using the WebDAV protocol is that it also makes it possible to use many other systems besides Windows to store files. There are 3rd party apps and online services such as Google Drive, Dropbox, OneDrive, Evernote that use the WebDAV protocol to access any server that's part of the ecosystem, as long as it supports WebDAV.

If you're curious about WebDAV you can also look at this page which contains more details. Now if you're wondering about the safety of using WebDAV it's really safe when used properly. Most people use WebDAV simply to upload files from their local computer to the cloud so you never see what goes on behind the scenes. The only reason why you would ever need to worry about the security of the connection between your PC and the WebDAV server is if the files are sensitive information that could be abused or taken.
