Types of Domain Variations Supported
These types are created by leaving out a letter of the domain name, one letter at a time. For example, www.goole.com and www.gogle.com
These types are created by repeating a letter of the domain name. For example, www.ggoogle.com and www.gooogle.com
Adjacent Character Swap
These types are created by swapping the order of adjacent letters in the domain name. For example, www.googel.com and www.ogogle.com
Adjacent Character Replacement
These types are created by replacing each letter of the domain name with letters to the immediate left and right on the keyboard. For example, www.googke.com and www.goohle.com
Double Character Replacement
These types are created by replacing identical, consecutive letters of the domain name with letters to the immediate left and right on the keyboard. For example, www.gppgle.com and www.giigle.com
Adjacent Character Insertion
These types are created by inserting letters to the immediate left and right on the keyboard of each letter. For example, www.googhle.com and www.goopgle.com
These types are created by omitting a dot from the domainname. For example, wwwgoogle.com and www.googlecom
These types are created by omitting a dash from the domainname. For example, www.domain-name.com becomes www.domainname.com
Over 8000 common misspellings from Wikipedia. For example, www.youtube.com becomes www.youtub.com and www.abseil.com becomes www.absail.com
Swap vowels within the domain name except for the first letter. For example, www.google.com becomes www.gaagle.com.
Over 450 sets of words that sound the same when spoken. For example, www.base.com becomes www.bass.com.
One or more characters that look similar to another character but are different are called homogylphs. An example is that the lower case l looks similar to the numeral one, e.g. l vs 1. For example, google.com becomes goog1e.com.
Wrong Top Level Domain
Wrong Second Level Domain
Uses an alternate, valid second level domain for the top level domain. For example, www.trademe.co.nz becomes www.trademe.ac.nz and www.trademe.iwi.nz
Each letter in a domain name is an 8bit character. The character is substituted with the set of valid characters that can be made after a single bit flip. For example, facebook.com becomes bacebook.com, dacebook.com, faaebook.com,fabebook.com,facabook.com, etc.
The output will often be wider than the width of your terminal. If this bothers you, output your report to a file or increase the width of your terminal.
Keyboard layouts supported are
Is the domain valid?
UrlCrazy has a database of valid top level and second level domains. This information has been compiled from Wikipedia and domain registrars. We know whether a domain is valid by checking if it matches toplevel and second level domains. For example, www.trademe.co.bz is a valid domain in Belize which allows any second level domain registrations but www.trademe.xo.nz isn’t because xo.nz isn’t an allowed second level domain in New Zealand.
