Explained: How is My IP Assigned / Determined (IPv4)?

Infopackets Reader Izzy M. writes: " Dear Dennis, I am trying to figure out how IP addresses are assigned using IPv4 (IP addressing version 4), but can't seem to find a straight answer online. My question: is there a certain number that my IP ... address has to be? Is there any correlation between my IP address, subnet mask and default gateway? How is my IP address assigned or determined? Thank you in advance! " My response: I think the reason you can't find an answer to this question is because this is an extremely broad question. To put this as simple as possible: the answer to your question ... (view more)

700 Million Email Accounts Hijacked by Spammers

More than 700 million email addresses and passwords have been leaked online. While many are bogus, enough appear to be genuine that security experts have advised users to change their email passwords. The collection of account details does not ... appear to have been used for identity theft or other fraud. Instead, the collection has been marketed as a way to send spam messages. The idea is that spammers can login to the compromised accounts in order to send their unsolicited emails. This effectively flies under the spam radar, as most spam comes from IP addresses without any reputation. In this ... (view more)

Smart Devices Likely to Cause Internet Congestion

One of the key figures in the creation of the Internet has warned that adding billions of gadgets with online connections could mean a slower Internet for many users. Vint Cerf said users need to enable a newer Internet addressing system to get the ... best results. Cerf is sometimes referred to as one of the "fathers of the Internet." He played a key role in the creation of ARPANET , the military network that established many of the technologies that were later at the heart of the Internet. Cerf also helped design the basic system by which Internet data is broken into small pieces, ... (view more)

Web-Wide Scan Reveals Shocking Security Weaknesses

In one of the most spectacular research projects ever carried out online, an anonymous security researcher has scanned the entire Internet for security holes. They found that millions of devices have no password protection whatsoever. The project ... was simple in concept: the researcher tried to contact and then access devices by trying every possible IP (Internet Protocol) address using IPv4, a system by which every device connected to the Internet uses 12 digits as identification. This means that IPv4 allows for a maximum of around 4.2 billion IP addresses. The researcher tried to contact ... (view more)

DNS Changer Virus: Internet Access to be Cut July 9

People whose computers are infected with the ' DNS Changer ' virus will lose access to the Internet on Monday, July 9, 2012, unless they take steps to remedy the situation. Right now the Federal Bureau of Investigation is wrapping up an operation ... designed to help such victims maintain their online connections. DNS Changer is named after the domain name system that helps translate website addresses (such as www.infopackets.com ) into a string of numbers known as an IP address, which is the way computers actually identify the machine where a particular website is physically stored.

Facebook Wipes Out User Messages, Contact Lists

After quietly changing the default email addresses of all its users to @facebook.com, on their profile pages, Facebook is now being blamed for causing multiple unwanted (and unwarranted) address book changes. The end result: an even fiercer backlash ... from Facebook's member base than we saw just a few days ago. It was bad enough when Facebook decided to overstep its boundaries and force an email change on all its users, whether or not they had agreed to sign on for the new email service. But further tensions arose when the company also decided to splash those new email addresses across each ... (view more)

New IP Addresses Safer, but Difficult to Implement

The current address system for computers connected to the Internet (TCP/IP version 4) is entering its twilight. And while the process of introducing a successor is ready to go, critics suggest it is a complex and challenging undertaking. The ... addresses in question are not website addresses: those have many more unused possibilities, albeit many of them hardly memorable or corresponding to common words. Instead, the problem is with Internet Protocol (IP) addresses, which correspond to an individual machine connected to the Internet, whether that be a standard computer or a server hosting a ... (view more)

Internet Governing Body Introduces Major Changes

The Internet Corporation for Assigned Names and Numbers, which is the closest thing to a web-wide governing body, has made several key changes to the way website addresses will work. It's added Chinese character addresses, backed a dedicated adult ... domain, and taken a further step towards tighter Internet security. The addition of Chinese characters follows a similar move last month, when Arabic script was included. It means for the first time the entire address can be written in the script, including the part at the end which indicates a country. To avoid confusion, the system isn't used for ... (view more)

Phishing, Malware both Blamed for Hotmail Breach

A security researcher claims a virus probably led to the compromising of 30,000 email passwords. However, most other sources continue to blame phishers. The email details appeared in two lists published by a user on a legitimate website designed for ... developers to share code. The first list included details of 10,000 Windows Live Hotmail accounts , while the second boasted 20,000 . Mary Landesman of ScanSafe says that while investigating a piece of malicious software in August she discovered the people controlling it had around 5,000 Hotmail user names and passwords which appeared to have been ... (view more)

Hiding Addresses when Using a Distribution List

If you include a distribution list in the To or Cc box of an email message, all of the recipients -- whether members of the distribution list or not -- can see the addresses of individuals in the lists. Outlook does not retain the list name in the ... address field of the message but instead replaces it with the actual addresses from the list. In some cases, the members of a distribution list may not want to have their addresses made public, even to other members of the list. In these situations, address the message using the Bcc box, rather than the To or Cc box. To display the Bcc box in the ... (view more)
