CHECK DNS
DNS Propagation Checker - South Africa & Global Lookup
Use the Cape Portal DNS Propagation Checker to look up live DNS records for any domain or hostname from a South African vantage point. Our tool checks a carefully selected list of public DNS resolvers with African points-of-presence in Johannesburg, Cape Town, Durban, Nairobi and Lagos, plus global locations in London, Frankfurt, Amsterdam, New York, Singapore, Sydney and Sao Paulo, so you can see exactly how a DNS change is propagating around the world.
This is especially useful after updating DNS settings, moving a website to a new South African host like Hetzner or Afrihost, changing email providers, switching nameservers at registrars like UniHost or DomainDiscount, or troubleshooting why a South African visitor sees a different result than someone overseas.
Check A, AAAA, CNAME, MX, NS, TXT, SOA, PTR, CAA, DS and DNSKEY Records
Different DNS record types perform different jobs. An A record points a domain to an IPv4 address, while an AAAA record is used for IPv6. MX records help direct email to the correct mail servers (important for South African businesses using Gmail, Microsoft 365 or local hosts like xneelo). TXT records are commonly used for verification, SPF, DKIM and DMARC email authentication.
CNAME records create an alias from one hostname to another. NS records identify the nameservers responsible for a domain. SOA records hold zone authority information. PTR records map IP addresses back to hostnames for reverse DNS. CAA records control which certificate authorities may issue SSL certificates for your domain. DS and DNSKEY records support DNSSEC signing.
Compare African and Global DNS Responses
DNS information can be cached by resolvers in different regions. After making a DNS change, a resolver in Cape Town may return updated information while one in New York still shows an older cached response. By checking both South African and international points at the same time, Cape Portal helps you understand the propagation status from the perspective of your local customers and your global audience.
Why DNS Changes Can Take Time in South Africa
DNS records are normally cached according to their TTL, or time to live. When a DNS record changes, South African ISPs such as Telkom, Vodacom, MTN, Rain, Fiber Tiger and Vox that already have the previous information cached may continue returning it until their cached value expires.
This is why a website or email service can sometimes appear correctly configured from one South African connection while another ISP, or a user in Europe, still shows different DNS information. Using a multi-location propagation checker is the fastest way to spot these regional differences.
When to Use a DNS Propagation Checker
- After moving your website to a new South African hosting provider
- After changing your domain's A or AAAA record to point to a new server IP
- After switching email or MX records for your .co.za domain
- After adding or changing TXT verification records for Google Workspace or Microsoft 365
- After changing nameservers at a .co.za registrar
- When troubleshooting a .co.za domain that is not resolving for certain customers
- When checking whether a recent DNS change is visible to both SA and international resolvers
- Before launching a new South African e-commerce or business website
- When setting up SPF, DKIM or DMARC records to improve deliverability to SA mailboxes
DNS Checking for South African Small Businesses
DNS problems affect more than just a website. Incorrect DNS records on a .co.za domain can cause website outages, prevent email from reaching customers, break domain verification for services like Google Search Console, and cause issues with payment gateways such as PayFast, Yoco or Peach Payments.
A quick DNS lookup from both local and global perspectives can help identify whether the expected record is being returned before investing time investigating more complicated hosting, website or email configuration issues.
Frequently Asked Questions
What is DNS?
DNS, or the Domain Name System, translates domain names such as yourbusiness.co.za into information that computers and online services can use to locate websites, mail servers and other services. Without DNS, South African internet users would need to remember long IP addresses instead of easy-to-use domain names.
What is DNS propagation?
DNS propagation describes the period during which updated DNS information becomes available through different DNS resolvers and cached networks worldwide. The time required can vary depending on caching and the TTL of the previous record. In South Africa, propagation to all ISPs can sometimes take up to 48 hours, although major public resolvers often update within minutes to a few hours.
Can this tool check every DNS server worldwide?
No. The tool checks responses from selected public DNS resolvers that operate African and global anycast networks, including Cloudflare and Google Public DNS with points-of-presence in South Africa. It cannot directly test every ISP, corporate network or local DNS cache inside South Africa or around the world.
Why does one resolver in SA show a different result than one overseas?
Different DNS resolvers can temporarily return different information because of caching, TTL settings, DNS configuration or anycast routing differences. Comparing multiple African and international resolvers can help identify these differences during a DNS change.
How long does DNS propagation take in South Africa?
There is no single fixed propagation time for every DNS change. Cached DNS information can remain available until the relevant TTL expires. For South African domains (.co.za, .org.za, .net.za), most public resolvers pick up changes within a few hours, but some ISP caches can take the full 48 hours to refresh.
Which DNS record should I check?
For a website address, an A or AAAA record is usually relevant. For domain email, check the MX record and related TXT records (SPF, DKIM, DMARC). TXT records are commonly used for verification and email authentication, while CNAME records are often used for hostname aliases and NS records identify a domain's nameservers.
Why do I see different results in Johannesburg vs. Cape Town?
South Africa is a large country with multiple internet exchange points (INXes in Johannesburg, Cape Town and Durban). Different anycast DNS providers may route Johannesburg users to one edge node and Cape Town users to another, and those nodes can refresh their cache at slightly different times. This is normal and expected during the propagation window.
