CIDR stands for Classless Inter-Domain Routing and is a method for allocating IP addresses as well as for IP routing. It was introduced in 1993 by the Internet Engineering Task Force to replace the previous classful network addressing architecture on the internet. When choosing a CIDR range for your network, the following chart will show you how many maximum IP’s you can have on that network. For example, /32 will give you 1 usable IP, /24 will give you 256 usable IPs, while /3 will give you 512 million usable IPs....

So you’re about to be featured on some very high ranking website. You’re worried that when all the visitors come rushing towards you, your web server?is going to crash and burn.?Well, you’re probably right! Did you know that 95% of all websites on the internet are not able to handle more than 30 concurrent visitors the way they are setup?

At this stage you select “Actions” and choose the “Detach VPC” option. In a perfect world, this would return a “success” and the IG would be deleted. But sometimes this isn’t the case and you have to do a little more. In this instance, you need to figure out what other services (network resources) are using this IG....

Squid is a proxy software that allows a computer without internet access to proxy through another computer that does have internet access. Squid is very easy to get setup and the computer that needs internet just needs to specify environment variables called HTTP_PROXY and HTTPS_PROXY which have the value of http://squid.ip.address:3128/ The complication comes in where you need a Squid instance (sitting on an EC2) to sit behind an AWS load balancer....

Cyber forensics is hard, but it is even harder when servers are hosted in different geographical locations and an investigation needs all localities to cooperate and hand over every part of the data consistently. This is primarily due to privacy laws that each region may apply or carry out in differing ways. Multiple regions Even if a compilation can source multiple regions data; dealing with international governments could mean prolonged wait times, unfamiliar processes to follow or even citizens of those regions withholding data due to privacy rights within that region....

Whether it be small and quite pathetic or just another reseller of a larger service trying to get their cut of things, everybody truly is spamming the world with more and more web hosting packages.
