Is it safe to use OpenDns
OpenDNS is a solution for the Domain Name System, i.e. for the background service that converts domain names into IP addresses. This means that users can type user-friendly domain names into the web browser instead of cryptic IP addresses. Typical DNS servers used by most Internet Service Providers (ISP) only convert the basic domain name into an IP address. Before the conversion into an IP address, the DNS filters are activated and, if necessary, block the conversion, if this has been set.
Since it's all DNS based, you don't have to use any software to use OpenDNS. Instead, you are simply replacing the DNS address on your router to protect your entire network. Or you can only change the DNS server on certain computers if you only want to restrict Internet access there. If you only change the DNS address on the computer, only this is affected by the DNS filter and is therefore protected.
You can use OpenDNS in three ways, depending on the features you want to use.
With the basic version you change the original DNS address on your router or computer against the main OpenDNS address: 188.8.131.52 and 184.108.40.206. Without a user account, these DNS addresses offer blocking of phishing sites. It also helps you protect your identity and there are a few additional DNS security functions.
Another option is to replace the original DNS server on your computer or router with the "FamilyShield" OpenDNS address. Family protection is activated via 220.127.116.11 and 18.104.22.168. Adult sites are automatically blocked even without a user account. In addition, many proxies and anonymization pages are blocked so that the protection cannot be bypassed so easily. Some phishing and virus-spreading websites cannot be accessed either.
The third option involves creating an OpenDNS user account. Then use 22.214.171.124 and 126.96.36.199 as main addresses. With a user account you can determine which types of pages should be blocked. You can also monitor internet usage. To test, you can start with a free account and, if necessary, switch to a premium account. With this you would in turn have further setting options.
While you are signing up for OpenDNS, you can get some help setting up your network or router properly. After you have logged into your dashboard, you need to add a network to your user account. If you are already on the network you want to protect at the time, click the "Add this Network" button to add the public Internet IP address to this user account.
However, you should know that your OpenDNS user account must always know your current IP address in order for it to work. But most home and small business networks use dynamic IP addresses that change regularly. Therefore you have to make sure that OpenDNS is informed of the correct IP address.
You can either do this using a simple update application that is installed on a computer, or you can configure your router's DNS settings to perform the update. If you want to go via the router, you can use the free DNS-O-Matic service if the integrated DDNS client does not support HTTPS updates. You can use your Open-DNS username and password to log into DNS-O-Matic. There you add OpenDNS as a service and configure your router so that it sends the current IP to the DNS-O-Matic account. DNS-O-Matic then forwards this information to OpenDNS.
