Barskertos

About

This Chrome extension checks DNS A-type record, server availability and redirection absence for sites with user-specified pattern(s) as a name(s). It is used to find sites with a specific name(s) registered on different domains (for example: football.com, football.co.uk, football.ge, football.lv etc).

Usage steps:
1. Enter a site name (as displayed on pic 1) without quotes and domain. For example: football. You may use patterns to generate multiple names. For example, the pattern gr{a|e}y-colo{r|ur} will produce such names as: gray-color, gray-colour, grey-color and grey-colour.
2. Check the checkbox "Use extended domains list" (as displayed on pic 2) for more accurate search among 1300+ domains. The list of most popular first level domains will be used otherwise.
3. Press "Search" button.

1. At first, Barskertos will list out all possible site names using entered pattern and selected domains. Every site in the list will be processed as follows:
2. DNS A-type record will be checked online using public Google DNS server (as displayed on pic 3). The site will be filtered out of list in a case of record absense or incorrect site status.
3. Server availability will be checked online (as displayed on pic 4) by sending an AJAX GET request to the site. The site will be filtered out of list in a case of connection error, timeout, redirection etc.
4. Scriptable redirection absence will be checked by opening a dedicated Chrome tab and waiting for site to load and run its scripts. The site will be filtered out of list (and corresponding Chrome tab will be closed) in a case of some script redirects Chrome tab to other URL.

Finally, the list of registered sites without redirections (as displayed on pic 5) is presented to the user, as well as Chrome tabs for each of them.
