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.
The Domain Name System is an important part of the Internet infrastructure that enables the correct resolution of DNS names, such as the name of a website. The system is built on a set DNS recursive solvers and authoritative names servers that process DNS requests sent by clients such as 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 DNS namesserver then is queried by a recursive DNS. The answer to this query is returned to the client.
The attacker can attack an open DNS resolution in a variety of ways, but the most common one is to send fake DNS queries with the victim’s IP address set as the source. Once the attacker creates a cached DNS record that is large, the open DNS will fetch this record and send to the victim’s IP address so long as they keep sending fake DNS questions.
To avoid these attacks, configure the DNS server to accept only queries from certain IP addresses. In an enterprise network, it would be a private RFC 1918 IPv4 or global IPv6 address block.
It is possible to achieve this by setting up a DNS fire wall to limit the access to a recursive resolution. It can be done via the external interface of the DNS resolver, which spans the internal and the external network. Or by limiting the recursive DNS query on the internal networks to the hosts in the subnet.
An open DNS resolver is a type of recursive resolver that accepts recursive DNS queries and resolves them in the same way as traditional recursive resolvers. These servers differ from the default DNS service provided by ISPs in that they offer different services, like faster or more robust ones. They may also censor certain names according to policy settings.
Google's Public DNS, for example, is a popular open DNS resolver that is used by many users as their primary resolver. 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 has a few features that help detect malicious DNS traffic. It is possible to log DNS traffic, including the query type, resolved DNS records, resolver locations, and other metadata, for non-profit operations research.
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. This indicates that there are many network providers who use these servers as their primary DNS resolvers or as backups.
