  • Today, 30 November 2010, the IANA allocated four /8s to the RIRs – 23/8 and 100/8 to ARIN and 5/8 and 37/8 to RIPE NCC. This leaves only seven /8s remaining in IANA free pool of IPv4 addresses, or 2.73% of the total. When the IANA IPv4 free pool has only five /8 blocks remaining, they will be simultaneously distributed to the five RIRs in accordance with global policy. This means that only two blocks remain to be handed out under the normal distribution method. With so little IPv4 address space left in the global free pool, ARIN continues to emphasize the need for all Internet stakeholders to adopt the next generation of Internet Protocol, IPv6. Visit https://www.arin.net/knowledge/v4-v6.html for more information on IPv6 adoption, or contact us at info@arin.net with any questions.

  • Note to webapp developers: the + character is a valid part of an email address. Don't stop me from using it. And fix your broken CGI parsing so + isn't treated as space. The + has a very useful meaning in almost all mailers: stuff after it is ignored. Ie, xyzzy@example.com and xyzzy+foo@example.com are basically treated as the same email address by example.com's mailer. Both addresses deliver to the mailbox owned by xyzzy. This has been a feature of sendmail for at least 10 years. It works in Postfix and qmail, too. The plus sign makes it easier to track how your email address is spread around. If I ever get email to nelson+cheapviagra@monkey.org, I know who to blame. It's also helpful if you're debugging webapps and need to create email-keyed accounts.

  • This tutorial will help you to install and set up a few email accounts, by using the built-in POP3 Service in Windows Server 2003. I will assume you have basic knowledge about the Windows Server family and Mail Servers, but I have tried to make this tutorial as easily comprehensible as possible. The tutorial has been tested on Windows Server 2003 Enterprise Edition but should also work on Windows Server 2003 Standard Edition. I will not cover MX records and other similar things in this release. To follow this tutorial you need a stand alone server. You can of course use a Domain Controller, but that assumes you understand when to not follow the tutorial and use other settings (i.e. authentication method).

  • Website security is an interesting topic and should be high on the radar of anyone who has a Web presence under their control. Ineffective Web security leads to all of the things that make us hate the Web: spam, viruses, identity theft, to name a few. The problem with Web security is that, as important as it is, it is also very complex. I am quite sure that some of you reading this are already part of an network of attack computers and that your servers are sending out spam messages without you even knowing it. Your emails and passwords have been harvested and resold to people who think you need either a new watch, a male enhancement product or a cheap mortgage. Fact is, you are part of the problem and don’t know what you did to cause it. The reason is that security experts don’t like to talk too much in public about what they do and where the issues lie; and sadly enough, they can also come across as arrogant in their views.
