Tech Contact
The technical point of contact for a domain, traditionally responsible for DNS and operational issues.
The technical contact is one of the legacy RDAP/WHOIS roles, originally meant for the engineer responsible for the domain's DNS, hosting, and operational matters. Like the admin contact, most public tech contact data for gTLDs was redacted after GDPR took effect in 2018. The role remains useful for ccTLDs that still expose it, for enterprise domains where it points at a NOC, and as a structured field in RDAP that incident responders can extract programmatically.
