SRVService host, port, priority300 to 3600sLocates services like SIP or Microsoft 365

How This Tool Works

This tool sends a real DNS over HTTPS query from your browser directly to dns.google/resolve or cloudflare-dns.com/dns-query, whichever you select. No query passes through WritoryBuzz servers. The resolver you choose queries the domain's authoritative name servers and returns the records directly to your browser.

DNS Propagation, Honestly Explained

When a DNS record changes, the old value can stay cached at any resolver until its TTL expires. A genuine global propagation check requires querying from servers in many physical locations, which a browser-based tool cannot do. What this tool can honestly offer is a comparison across several independent public resolver providers, useful for spotting whether one major provider is still serving a stale cached answer.

To speed up propagation before a planned change, lower your record's TTL to around 300 seconds 24 to 48 hours in advance, then restore it once the change has settled.

Frequently Asked Questions

What is a DNS lookup?+
A DNS lookup queries the Domain Name System to translate a domain name into the IP addresses, mail servers, and other records computers use to route traffic. Without DNS, every URL would need to be typed as a raw IP address.
How long does DNS propagation take?+
Typically between a few minutes and 48 hours, depending on the TTL set on the old record. A TTL of 3600 seconds means resolvers can serve the old value for up to an hour after a change. Lower the TTL in advance of a planned change to speed this up.
Does this tool store my queries?+
No. Queries go directly from your browser to Google DNS or Cloudflare DNS over HTTPS. No query data passes through WritoryBuzz servers.
What is the difference between an A record and a CNAME?+
An A record maps a domain directly to an IPv4 address. A CNAME maps a domain to another domain name, which then resolves further. You cannot use a CNAME on a bare root domain, so use an A record there and CNAME for subdomains.
Can this tool check DNS propagation across the world?+
Not in the geographic sense. It can compare results across several independent public resolver providers, which is useful for spotting stale caching at one provider, but a true global propagation check needs infrastructure physically located in multiple regions, which no browser-based tool can provide.
