Track Your Vendors and Eliminate Spam with Canary Domains

By , April 5, 2013

( User Level: General )

The other day I came across a great blog post that explained how the author setup a domain name with “catch-all” or “wildcard” email forwarding which enabled him to track which of his online vendors were selling his email address or otherwise spamming him.

This is called using “canary email addresses”, I’ve been doing it for a long time with my own personal email domain.

How Canary Email Addressing Works

You would grab a domain name separate from what you use for your main personal, work, hobby email and websites. It can be anything and it doesn’t have to be pretty because humans will rarely even see it. Read more »

Do You Need To Fix Your DNS Resolvers?

By , April 1, 2012

( User Level: Basic / Intermediate )

The other day we sent out our primer on the three different types of nameservers and why it serves your interests to know them and what role each one plays. In this post we concern ourselves with Resolvers – those nameservers we all use that do all the DNS lookups we require to conduct our routine activities on the internet.

DNS Changer: A Racket To Intercept Your DNS Queries

Paul Vixie (creator of the bind software that powers the vast majority of nameservers on the internet) recently related the story of “DNS Changer” and the role of his organization in taking it down. It reads like something out of a Tom Clancy novel, only this really happened:

( User Level: Basic / Layman )

The best way to understand the difference between DNS servers is to think of them in three groups which correspond to three basic aspects of the domain naming system:

How the Domain Expiry Cycle Works

By , October 29, 2010

One of the more confusing aspects around domain names is how they are released back into the pool of available names once they expire. People mistakenly believe that if a domain name expires on such-and-such a date, then they will be able to just hop on the computer and register it again the next day, or later the same day.

Not so.

The difference between a 301 and 302 URL redirect

By , July 7, 2010

I read this article about redirecting domains and also get asked this every once in awhile by customers: what is the difference between a regular “URL Redirect” (basically one done with a “302 Found” header) and a “301 Redirect” (done via a “301 Moved Permanently” header)?

There is no such thing as an "ICANN Accredited" Reseller

By , June 2, 2010

While looking into a web hosting company the other day I noticed they also had a “domain reseller” business and was surprised to see a pretty official looking ICANN logo that had the words “ICANN Accredited Reseller”. Read more »

The difference between "sunrise" and "landrush" phases of new Top Level Domain rollouts.

By , May 25, 2010

We published a few articles on our company blog about the forthcoming launch of the .CO top level domain, and we made numerous references to the “sunrise” and “landrush” phases without realizing that those phrases are “jargon”. People who don’t live and breathe domains may not actually know what this means!

How to link multiple domains to a website

By , April 24, 2010

Nick from the U.K asks:

My company recently purchased a couple domains and we want those to link to our current website. Eg. example.com will transfer to example.co.uk instantly. How can I do this?

Many Thanks,
Nick

This is similar to an earlier post How do I point “www.domain.com” at “domain.com” or vice-versa?, but since we’re going across multiple domains, we should also think about a couple additional issues.
