NetworkingAlso called: "dns", "name resolution"
DNS acts as the internet's phonebook, resolving names like example.com to IP addresses like 93.184.216.34.
DNS record types
- A/AAAA: IPv4/IPv6 address mappings.
- CNAME: Canonical name (alias) for another domain.
- MX: Mail server routing.
- TXT: Arbitrary text data (SPF, DKIM, verification).
- NS: Nameserver delegation.
Security concerns
- DNS hijacking: Attackers redirect queries to malicious IPs.
- DNS cache poisoning: Corrupt resolver caches with fake records.
- DNSSEC: Cryptographic authentication of DNS responses.
