New Service – IP Blacklist Monitor (2015/01/21 14:06)

We have published a new IP Blacklist Monitoring service. Any company with their own mail server or a dedicated IP address under its management will benefit from this service. However, our primary customers are hosting companies of all sizes, VPN providers, Internet service providers, universities, and other companies that manage IP ranges of any size.

The service was created in cooperation with a medium size server hosting company, for which we are now monitoring several thousands of their IP addresses already. This is why we believe that it is ready to help your company to deal with infection detection, TOS violations, spam sending clients, and similar issues that can be detected using DNSBL or RBL IP blacklists. Simply create a blacklist monitor and be notified when your IPs become listed on one or more blacklists or when they are removed.

We would like to invite you to try our blacklist monitor for free – up to 3 IP addresses checked on a daily basis against 150+ blacklists is provided completely free of charge. And if you like it and need to monitor more IP addresses, our prices are the best you can find on the market.

SERP Checker (2014/07/14 08:21)

Full name of our new tool is Keyword Rank SERP Checker. Probably all web masters and people around SEO and marketing know what this tool is supposed to do. For those, who are not familiar with SERP checkers – it is a tool that finds out how your project (website / domain) ranks for a specific keyword on Google (in general it can be done for other search engines as well, but we focus on Google, since its market share is unbeatable, maybe except for China). A SERP rank is simply a position in SERP, which stands for Search Engine Result Page, so rank 1 means that your web appears on the first place on the page with search results for a particular keyword. Obviously, this directly affects the number of visitors that will reach your website from this search (over 30 % of traffic generated by a search query goes to web that is ranked first).

We have created this tool simply because there are very few SERP checkers on the web that actually work and provide full information that users of these tools are interested in. Our tool also supports regional searching, so you are not limited to international, but you can find your rank on,, etc.

Heartbleed OpenSSL Bug Checker (2014/04/08 19:36)

Heartbleed OpenSSL Bug Checker based on Filippo Valsorda's open source Hearbleed checking tool has been added to Online Domain Tools toolset.

This online tool allows you to quickly check whether your online service is vulnerable to recently announced Heartbleed bug. A very serious problem has been found in OpenSSL versions 1.0.1 to 1.0.1f, which allows an attacker to perform a wide range of attacks once she takes advantage of the Heartbleed bug.
