An open DNS solver is a DNS Server that accepts DNS queries recursively from any IP Address on the Internet. Denial of Service(DoS) attacks are possible on these servers.
Domain Name System (DNS), an important component of Internet infrastructure, allows for the correct resolution DNS names like the name of website. The system is based on a set of DNS recursive resolvers and authoritative nameservers that process DNS requests from clients like browsers.
In most cases, the client will send a DNS query through its stub solver. This stub then forwards the query on to a resolver that recurses. The recursive resolver then queries an authoritative DNS nameserver for the root zone. The result of this query is then sent back to the requesting client.
One of the easiest ways to attack a DNS resolver is by sending bogus DNS queries using the IP address of the victim as the source. The attacker will generate a large cached DNS entry. Once this record is generated, the resolver open will retrieve it and send it the victim's IP as long as they continue to send fake DNS queries.
To avoid these attacks, configure the DNS server to accept only queries from certain IP addresses. In a typical enterprise network, this would be the private RFC 1918 IPv4 address space or an organization's assigned global IPv6 address block.
This can also be achieved by installing a DNS-firewall that restricts access to the resolver. This can be achieved on the external interface a DNS resolution that spans both an internal and external networks or by restricting recursive DNS requests on the internal network only to those hosts within that network subnet.
Open DNS is a recursive DNS that accepts recursive DNS and resolves it in the same fashion as traditional resolvers. There is a difference between open DNS resolvers and ISP's default DNS. Some of these resolvers offer more robust or faster services. Others censor names based on certain policy settings.
Google Public DNS is, for instance, a very popular open DNS solver in many places and is used as the primary resolver by over 1 in 5 users. The popularity of Google's Public DNS is probably due to the fact that it has a good reputation in the DNS sector and offers a reliable service.
Cloudflare Public DNS Resolver: This open resolver has many useful features for detecting malicious DNS Traffic. The Cloudflare Public DNS Resolver is another common open resolver. It has a number of features that are helpful for detecting malicious DNS traffic.
In the experiment a little more than one-sixth of users use open DNS as their primary DNS resolver. The number increases to almost 1 in three if the list is expanded to include full resolvers. These servers are being used widely and this indicates that network service providers rely on them to resolve DNS queries as their primary servers or as backups.
