If you are an average Internet user, you have surely heard about the term “domain name. This will not probably mean too much but without web hosting and domain name registration, people will surely have a hard time browsing through the Internet.

The web hosting and domain name registration can be compared to how the telephone system is used be the people. In fact, the telephone is one main element why we have Internet connection. Phone lines and without web hosting and domain name registration have a lot in common except that it is quite based on some electronically procedures.

If you are fond of surfing the web, you should make use of the web hosting and domain name registration without even realizing that you are. On the other hand, it is for the reason that you do not know what is taking place. When you ordered a telephone line or service, which is for your business or home use, the specific carrier that you are using assigns a particular number, which is exclusively for you only.

This is the same for the computers, which has a sequence of numbers, which is longer than the telephone numbers. This is made unique to your computer. The numbers that will be assigned to you when you apply for a web hosting and domain name registration is known as the IP address.

The IP address is also known as the Internet Protocol Address. The memorization of the numbers may be quite a tough job so the DNS have allowed it to be replaced with names that are distinctive. They have now allowed the business names to replace the numbers during the web hosting and domain name registration process.

The only requirement for a successful web hosting and domain name registration is that it should have no duplicate and it should be unique. You will be asked to provide your domain name so you should think of it properly and wisely.

It will be hard to come up with a domain name that is unique because almost all domain names are taken especially the frequently used ones. A lot of people have already made a web hosting and domain name registration which makes such domain names hard to be available.

If you want to successfully come up with a web hosting and domain name registration, you can look up into some of the sites that offer free domain names that are unique and fit for the theme of your site.

If you want to be an owner of a site, make sure that your domain name is well acquainted or it is similar to your company or product name so that the people will easily remember the name of your site with the help of the brand names and company names.

If you have a domain name that will easily be remembered, it will be a good advantage to your site. Some of the companies that accept web hosting and domain name registration will often refer you to registrars who check it into a list of directories that can be found online.

The process will include the technical information and all the other needed information. If you want to have a web hosting and domain name registration, make sure that you choose a good web company that can handle all your needs.

Spam Policy Framework (SPF) it will stop SPAM if used

I was reading a forum post today in which a forum member was complaining because an unscrupulous spammer was spoofing his domain an using it to send out large amounts of unsolicited email, SPAM. The forum user posted the domain in question so I immediately posted it in the form over at http://www.dnsreport.com , just as I thought the domain did not have a Spam Policy Framework (SPF) record in their Domain Name System ( DNS ) server.

It amazes me how many ISP’s still do not have a policy for requiring a SPF record in the DNS servers for the mail servers they manage mail for. I’m guessing a lot of people do not even understand the purpose of the Spam Policy Framework and why its important in preventing SPAM. Basically SPF is a method for telling other mail servers the authorized mail server for sending mail from a particular domain. It is very easy to implement and only takes one line in the DNS server zone if you are defining the mail servers for one domain.

SPF makes it really easy to define the authorized email servers for your domain. It works like this When someone sends an email message out and the receiving server attempts to do a reverse lookup on the domain then your DNS server replies hey I’m xyz.com and I only send email from my server mail.xyz.com. If you get email from any other server you should really deny it since it did not come from me and its not my mail.

So you can see SPF is an effective method for preventing unauthorized users from spoofing your mail domain and getting your servers listed as a spammer. I would say its in the top three of things you should do on your servers to help stop the proliferation of SPAM through out the world and to stop wasting all the bandwidth these spammers waste everyday. These three things that every email administrator should implement include: 

  • Close Relays – Don’t let other people bounce SPAM through your server. All major email servers allow for the definition of servers that are allowed to relay, but most people just don’t turn it on.
  • Define Reverse Lookups for your mail server—Many people now do this because most mail systems will not accept mail from mail servers without a reverse lookup record. This is a little harder to do, since it requires that the ISP either set it up for you or they must delegate your Internet Protocol ( IP ) scope to your DNS servers. This usually only works for companies when you have a range of IP addresses leased, but your ISP should do this for you if they are managing your email servers. If you are managing your own email servers and Domain Name Servers then you should really have the authority for the range delegated to you.
  • Spam Policy Framework—Implement SPF and tell the world which servers are authorized to send mail form your domain. It’s very easy to implement in the most simple form all it takes is the following line in your zone file:
    First you have you MX record
    Somedomain.com. MX 0 mail.somedomain.com.
    Somedomain.com IN TXT "v=spf1 mx"

Add this second line after your MX record in bind and you are done and your DNS server will send out the allowed email servers for your domain when someone requests it.

I hope that more and more Internet Service Providers will start to require this feature for all domains. I think once it becomes normal and receiving mail domains will stop accepting mail from domains without an SPF defined then you will start to see a reduction in the amount of SPAM on the Internet today.

After all, SPAM is a technical problem and no laws like the CanSpam Act are ever going to stop this problem. The technical infrastructure allowed the problem to start and the technical infrastructure can stop the problem as soon as network administrator’s start implementing every feature at their disposal. Once everyone starts using this then the SPAM filtering companies can deny any mail that does not have a SPF record without having to worry about false positives and that should help a lot. Right now on my domains I put you half way to a being defined as SPAM if you don’t have one of these records. If all the domains that send me mail had SPF implemented then I would give them all a 100% and quarantine the message immediately. Maybe one day I’ll be able to stop SPAM at my doorway.

10 G Network Upgrade

I received some quotes the other day to bring the majority of our backbone up to 10 Gigs. In order to accomplish this I will need to upgrade to an Enterasys X16 chassis. I originally wanted to leverage my a couple of existing N7 chassis to provide the 10 gig connectivity to the majority of the rest of the network. The plan is to provide a 10 G link to the areas of the campus where the majority of the users are located. Right now we have aggregated gigabyte links to each of the edge switches and that has worked fairly well, but I’m starting to see where these links are being saturated with Video and other multimedia media that is being used in instruction.

We are also in the midst of implementing a new PBX system that while will not be primarily a VoIP solution it does have that capability. While our initial implementation will only have a very small number of IP phones it will have the capability to add quite a few more phones in the future. I need to allow for that now as its seems we may have some funds to replace obsolete equipment and I’ve learned to strike while the iron is hot or those funds may not be available later.

Replacing this equipment will not only allow me to offer increased bandwidth to the majority of my users and we will even be able to allow a good number of users to experience Gigabyte to the desktop, it will also allow me to finally remove the remainder of the legacy switches in the network which will not support QOS and the level of security I like to enforce. This will help me obtain the level of User Personalized networking that I’ve always envisioned. Part of the quote I received includes Enterasys’s new Sentinel Trusted Access Gateway and Trusted Access Manager. This product allows you to bridge the gap between your intrusion detection system and Access Control lists which allows you to dynamically react to threats on your network. This is very important in a school environment where students are constantly connecting infected laptops to the network. I’ve implemented ACL’s where these accounts only have access to certain areas of the network, but I still have to allow them access to the student servers, so having a more complete solution like this will allow me to still offer these vital services while at the same time protecting us from the threats these uncontrolled computers may introduce into our network.
