CyD Careful Observer - Network Monitor 2010
CyD Careful Observer - Network Monitor 2010 is now available. The new version has a lot of features that will be useful to database administrators, web site owners and so on.
Now you can set any number of testers to one host. The older version allowed setting only one tester to each host. To configure two testers on one IP address you had to create two network items in the program. Now you have to create only one network item.
More information about new features may be found on the vendor WEB log. I recommend you to read the next record: New features of CyD Careful Observer - Network Monitor 2010

Speeding up DNS Operation
Every time you want to visit a site, for example to download a new version of a CyD Software Labs program, you enter the site's address as text data. In the case of our CyD Software labs, this will be www.cydsoft.com. But the actual site address is not the text name, but an IP address. An IP address (as used in the most common 4th version of the IP protocol) consists of four groups, each of three numbers, separated by periods.
Consequently, before the site can be loaded into whatever browser you are using, its IP address must be determined by its symbolic address (name). To get the IP address, the computer sends a request to the DNS server to translate the user-friendly name into the IP address. Only after the computer receives the IP address of the server of the site from the DNS can the connection be established and the site loaded into the browser. The address translation process can take some time, so the delay can be noticeable.
Why are DNS address-translation operations needed? Because humans are not particularly good at remembering numbers. It is much easier for us to remember meaningful text names, especially if they are associated with what we are interested in. Machines, on the contrary, use numbers in their operation. So, to build a bridge to connect humans and machines, the DNS system was designed to convert human-friendly text names into the numerical IP addresses used by computers.
