A recent report from Infoblox says the U.S. far and away hosted the largest number of domains that were used “for hosting and launching attacks using malicious DNS infrastructure” in the fourth quarter of 2015.

I’ve covered macvlans in the Bridge vs Macvlan post. If you are new to macvlan concept, go ahead and read it first.
To recap: Macvlan allows you to configure sub-interfaces (also termed slave devices) of a parent, physical Ethernet interface (also termed upper device), each with its own unique MAC address, and consequently its own IP address. Applications, VMs and containers can then bind to a specific sub-interface to connect directly to the physical network, using their own MAC and IP address.
Macvlan is a near-ideal solution to natively connect VMs and containers to a physical network, but it has its shortcomings:

So you’ve spent time asking what, observing the network as a system, and considering what has actually been done in the past. And you’ve spent time asking why, trying to figure out the purpose (or lack of purpose) behind the configuration and design choices made in the past. You’ve followed the design mindset to this point, so now you can jump in and make like a wrecking ball (or a bull in a china shop), changing things so they’re better, and the new requirements you have can fit right in. Right?
Wrong.
As an example, I want to take you back to another part of a story I told here about my early days in the networking world. Before losing the war over Banyan Vines, I actually encountered an obstacle that should have been telling—but I was too much of a noob at the time to recognize it for the warning it really was. At the time, I had written a short paper comparing Vines to Netware; the paper was, perhaps, ten pages long, and I thought it did a pretty good job of comparing the two network operating systems. Heck, I’d even put together a page showing how Vines Continue reading

Change control isn’t so bad. With the underlying goal of risk mitigation, good change control can save a network engineer from the dreaded resume generating event we sweat over during cutovers. Change management frameworks such as ITIL layer an element of bureaucracy over network operations to provide a basis for a quantitative approach to IT […]

We’ve recently added video streaming service to Mail.Ru Cloud. Development started with contemplating the new feature as an all-purpose “Swiss Army knife” that would both play files of any format and work on any device with the Cloud available. Video content uploaded to the Cloud mostly falls into one of the two categories: “movies/series” and “users’ videos”. The latter are the videos that users shoot with their phones and cameras, and these videos are most versatile in terms of formats and codecs. For many reasons, it is often a problem to watch these videos on other end-user devices without prior normalization: a required codec is missing, or the file size is too big to download, or whatever.
In this article, I’ll go into detail to explain how video playback works in Mail.Ru Cloud, and how we made the Cloud player “omnivorous” and ensured support on a maximum number of end-user devices.
