.ZA Domain Name Authority

What .ZA Domain Name Authority does

.ZA Domain Name Authority (ZADNA) is a not-for-profit statutory regulator and manager of South Africa's country code top-level domain (.ZA), established under section 59 of the Electronic Communications and Transactions Act 25 of 2002 and accountable to the Department of Communications and Digital Technologies (DCDT). It licenses and oversees a layered ecosystem of registry operators — ZA Registry Consortium (ZARC) for commercial SLDs (co.za, org.za, net.za, web.za), TENET for ac.za, SITA for gov.za, the e-Schools Network for school.za, and the Cape Law Society for law.za — and accredits more than 300 registrars that handle retail domain sales. Core products include the NIC.ZA information portal, WHOIS lookup, an Alternative Dispute Resolution (ADR) service (R10,000 one-adjudicator, R24,000 three-adjudicator panels) administered through accredited providers such as SAIIPL, and a DNSSEC Policy and Practice Statement (DPS) for the .ZA namespace built on OpenDNSSEC and BIND. The business model is regulatory and cost-recovery rather than commercial: ZADNA approves wholesale domain pricing (R61 per commercial domain from October 2024, a 5.23% CPI-linked increase from R55) but does not retain the per-domain fee, which accrues to ZARC and supports a non-commercial development fund. Revenue is augmented by ADR fees, registry and registrar licensing, and nominal training fees (R2,000 refundable reservation for DNS technical training). Customer segments span commercial businesses, government, higher education, schools, non-profits, legal professionals, network operators, and IP owners. Recent activity includes the October 2024 multi-year registration policy (up to 5 years), draft registry and registrar licensing regulations published in 2025, an RFI issued in May 2026 for post-2027 commercial registry services, and a DCDT governance investigation in 2024/2025 that triggered a R247,757.84 recovery action against the CEO and a broader governance reform programme.

Direct peers

• InternetNZ: Not-for-profit manager of the .nz ccTLD with member-based governance, registry oversight, and community funding programmes analogous to ZADNA's structure.
• DENIC: Germany's .de ccTLD registry operating as a not-for-profit cooperative, providing registry services, DNSSEC, and dispute resolution. Comparable in mandate, scale, and regulatory positioning to ZADNA.
• Registro.br: Brazil's ccTLD registry operated by NIC.br, a not-for-profit entity managing .br under a similar mandate of registration, DNSSEC, and policy oversight.
• Afnic: France's ccTLD registry operating .fr under a similar not-for-profit mandate with registry/registrar licensing, DNSSEC operations, and policy development. Afnic's regulatory and technical scope is highly comparable to ZADNA.

Regional players
