Can DNSSEC cause problems? Print

DNSSEC is designed to improve the security of DNS by adding a layer of authentication to DNS data. However, like any technology, it can potentially cause problems if it is not configured or used correctly.

Some potential issues that can arise with DNSSEC include:

  • Complexity: DNSSEC involves the use of digital signatures, public-key encryption, and other technical concepts that may be difficult for some people to understand. This can make it challenging to set up and manage DNSSEC effectively.
  • Performance: DNSSEC adds an extra layer of validation to DNS queries, which can potentially impact the performance of DNS lookups. In some cases, this may cause a noticeable delay in the time it takes for a DNS query to be resolved.
  • Compatibility: DNSSEC is not supported by all DNS resolvers and name servers. This can create compatibility issues if a DNSSEC-enabled domain is queried by a resolver or name server that does not support DNSSEC.
  • Configuration errors: As with any technology, it is possible to make mistakes when configuring DNSSEC. These errors can result in DNSSEC not functioning as intended, or in some cases, causing problems with the operation of the DNS system.

Overall, while DNSSEC can provide important security benefits, it is important to carefully consider the potential issues and risks associated with using it, and to ensure that it is properly configured and managed.
