Explanation

IPsec, VPN, and HTTPS are all encryption-based protocols specifically designed to protect data confidentiality and integrity while it is moving across a network (data in transit). DNSSEC (DNS Security Extensions), by contrast, is designed to authenticate DNS responses and prevent DNS spoofing or cache poisoning-it validates the integrity of DNS lookup results using digital signatures. DNSSEC does not encrypt data in transit between application endpoints; it secures the DNS resolution process itself, making it a data integrity/authentication tool, not a data-in-transit encryption tool.
