Ping (ICMP)
Ping (ICMP) Ping is request message for protocol ICMP.

Ping is request message for ICMP (stands for Internet Control Message Protocol). This protocol is used by different network devices to check if a service or a device is available. Usually it is used for network diagnostics.

Ping monitoring allows you to keep an eye on your network infrastructure. Ping failure means broken connection to a network entity. It is handy to use Ping together with HTTP monitoring. In this case, you get additional information - for example, you know if the error is site-related, or the whole server has gone down. However, sometimes ICMP could be blocked for incoming requests, in order to prevent ddos attacks.

Perhaps your IP-address is already blacklisted but you don’t even know ...

Anyone can be blacklisted – so what can you do? How can you detect such problem? Are there any protection mechanisms? This is what this article is about.

Are you sure that your domain isn’t currently listed with some anti SPAM-database? We recommend you to check this out!  As you can be one of those who accidentally fall into being blocked due to spreading spam, malware, viruses or just having dangerous, illegal or prohibited content (links to such content) hosted on their pages. Apparently, anyone can be blacklisted – so what can you do? How can you detect such problem? Are there any protection mechanisms? This is what this article is about.

Why is this happening?

There are tens of thousands of different DNSBL-servers up for grabs out there and they all have their own set standards and criteria for which IP should be blacklisted. Moreover, these conditions are constantly changing. Therefore, there’s no guarantee that even a law-abiding domain which meets all standards of copyright and trademark laws, the laws of privacy and publicity, and other applicable regulations and statutes of law, one day wouldn’t be filtered out by the search engine as one that spreads spam.

Actually, HostTracker’s team recently faced the risk of being banned too. HostTracker, in its capacity as a website monitoring service, sends daily many various reports to the people that requesting them, hence it was easy to determine that some of our emails hadn’t been delivered and were dumped into a spam folder.

So what should you do?

Understanding the problem is the first step to fixing it. So it’s crucial to be aware of the warning signs of listing threat and be able to quickly take steps to cut back if you recognize them. Since we recommend adopting our new feature - "DNSBL" on the "Check site instantly" bar - we have implemented just for you:

This option is not exactly brand new, as there are dozens of different check services out there (for instance, Mxtoolbox), which offer a convenient help in testing whether your domain is on some blacklists. But soon we realized that we also needed to arm HostTracker with this check, as without having had such tool in place, we were flying blind.

In light of what was written above, we provide the illustration of how the "DNSBL" check works:

If HostTracker detects some suspicious activity from your IP address, you’ll be notified immediately with an alert of a possible listing reason. For you it means - the ability to track the reason why the site was blocked to its origins.

Usually, the domain will be blocked not at once but only after a thorough analysis of many factors. If you have already discovered your IP on one or more blacklists, don’t panic, more often than not, all you need to do is to follow their specific removal process. That implies, you should visit the corresponding blacklist's website and, following the removal instructions, enter the domain name and press "Delist". Additionally, you may need to contact the blacklist with a removal request. Note that, previously you have to resolve all issues that caused the blacklist.

So, if you happen to discover your IP address involved in spamming – resolve the underlying issues and you’ll be removed automatically, once a certain period of time elapses. How to stay protected and off of blacklists? The best option is to use PTR or SPF for messaging, as this’ll eliminate the likelihood of your domain name getting fraudulently spoofed and abused by spammers, or blocked for appearing to use a dynamic IP address.

There's no single cause of being blacklisted. Generally speaking, if your IP has been tagged illegal accidentally, the removal process won’t take much time and effort. But it is essential to be proactive, so that to be able to act fast and be in tune with such situations. The sooner you find out about the issues, the easier they are to deal with and the more likely that your domain name won’t be deemed illegal among the entire set of DNSBL databases. Use our new option "DNSBL" on the "Check site instantly" bar to be always aware of the "status" of your resource and never be tossed and turned by the tides of website hassles and outages. Remember, we’re looking forward to any interesting comments and suggestions regarding our service and its work.

▶ Monitoring domain and SSL certificate expiry dates.

▶ How to activate the SSL certificate monitoring tool and domain monitoring settings?

▶ It takes only several minutes with HostTracker. 

So many domain names are lost in this fashion. The domain name holders have their names taken away by others, simply because they miss the renewal alerts and they do not notice when their domains are not running the show anymore. Although the whole system for domain name holders is not very practical or sensible, reality confirms that dropping a domain name is a significant problem nowadays. Anyone who holds a domain name is very much prone to losing it, ranging from big corporations, like Microsoft, to small private firms. Trying to solve this problem, HostTracker has developed utterly useful tools that highly increase the chances to reach 100% uptime.

Controlling tools

Registrars are obliged to keep the registered name owner always updated on the status of a domain and must notify of the impending expiration at least two times. One of these notifications must be sent about one month prior to expiration and one must be sent about one week prior to expiration. But “In theory, theory and practice are the same. In practice, they are not”. That’s why a lot of very bad things keep on happening. For instance:

  • Alerts go to the spam folder;
  • Responsible employees are taking time off work;
  • Or just there is something more important that should be solved just at this moment and the domain renewal is put off for the better times.

Problems like these occur very often.  Moreover, when we face them - no one can recall the timing of the registration, the timing of payments, the cards from which the money was written off etc.

Are you getting the idea that it’s truly important to pay attention to this stuff? Use HostTracker tools. The service will monitor your domain/SSL certificates for many different status changes, such as when a domain becomes registered, when it drops and becomes available, when it's renewed and everything. You can enable automatic summary reports that are emailed on a daily / weekly / monthly basis (or at any interval you choose). The reports can include renewal dates of registration and any other useful information and can be sent, for example, via SMS, email or a Skype. These instruments are also fully configurable and can be used together or separate with regular uptime checks.

Domain Monitoring Service Settings

Applying domain monitoring settings takes several minutes:

simply enter the domain name. You can click on "Add list" to monitor more than one website. You may also configure additional options by clicking on "Subscriptions" bar:

  • “Up” - the domain renewal notices are emailed one month, 7 and 3 days prior to expiration.
  • “Down” - you are notified that your domain name has already expired.
  • “Repeat” - you receive alerts every day until you renew the domain name.

Put tick marks next to the contacts of people, who should be informed in case of any problems.

If you want to be notified not only by email, but also by other messengers (Skype, Hangouts, Telegram), add them in the "Add Contact" bar or in the "Notifications" menu on the main page screen.

How to activate the SSL certificate monitoring tool

Since Google announced that they’re going to be using whether or not a server uses SSL as a ranking signal, the number of people interested in purchasing SSL certificates has skyrocketed. Why are SSL/TLS certificates so beneficial? 

The idea of using SSL/TLS certificates is crystal clear, as it is a type of encryption used for securing web sessions. HTTPS keeps both your websites and your customers' personal information private and secure. As when a SSL certificate is used, the information becomes indecipherable to everyone besides for the server you are sending the data to. This protects it from "domain slamming", "email phishing" attacks and other harmful activities.

Therefore, it is vital not to miss SSL/TLS certificates expiry dates. Both domain monitoring and SSL monitoring instruments are operating alike and have the same configuration, which includes:

  • Sending renewal notifications 30, 7, and 1 days prior to certificate expiration.
  • Sending instant reports when security certificate is becoming “off”.
  • Reporting daily about the necessity to renew the SSL/TLS certificates.
  • Selecting groups of contacts who can be informed in case of a crisis/emergency.

With activating the two monitoring functions in the Business or Enterprise packages, or in a trial mode, you’ll be always aware of the certificate or domain expiry dates. Or at least, in case of unintentional domain losses, you will be eager to know the reason when, why and how it has happened and sort out the problem.

HostTracker is client-focused

That’s why one of our founding principles as a company included remaining flexible and adaptable, as well as open to improving our service. As the technology world changes, we’ll be ready to make quick, minute adjustments, add new tools and implement new features to improve our product.
