Guide

DNS lookupCommon searches and answers

A DNS lookup shows where a domain resolves. A is IPv4, AAAA IPv6, MX mail, NS nameservers, TXT proofs and CNAME an alias. This page answers “what is a DNS record”, “how to check MX” and “how long DNS takes to propagate”. Webify lists the records in one run; query only your own or authorised name.

Record types and daily work

The browser asks NS first, then A or AAAA. A wrong A record sends the site to another host; a leftover IP causes “sometimes the old site opens”. Missing or wrong MX drops mail. TXT holds SPF, DKIM and DMARC fragments; a broken quote or duplicate record breaks delivery. CNAME maps www to the apex; a CNAME on the apex can clash with MX.

TTL is how many seconds a record stays cached. Low TTL helps a cutover; high TTL cuts query load on a quiet site. After a change wait 300–3600 seconds; “still the old IP” is often a local cache. On Windows use ipconfig /flushdns; on a phone, airplane mode.

Mail and verification records

MX tries the lowest preference first. Google Workspace and Microsoft 365 need their own MX template; a leftover host MX mixes spam and loss. SPF must live in one TXT; two SPF strings are invalid. The DKIM selector is set in the panel. Without DMARC a spoofed From is easy. This tool lists TXT as-is; it does not write policy.

Propagation, CDN and www

A CDN or WAF pulls the A record to its anycast IP. If you leave the origin IP in A, both CDN and origin answer; certificates and cookies break. www is usually CNAME, apex is A; pointing both at origin inconsistently fails. After a DNS change, TLS must cover the new IP.

The tool asks a public resolver; a corporate VPN may see another answer. Repeat the query on a second network (mobile data) to compare. Do not scan someone else’s name; that hits quotas and the law.

When to call Webify

If records look right but the site or mail is still down, the fault is server, firewall or certificate. In the Beylikdüzü office DNS, SSL and MX are locked in one window. This page is diagnosis; it does not write records. You or an authorised tech apply changes in hosting or the registrar panel.

Search intent and a checklist

People search “what is a DNS record”, “how to add an A record”, “Google MX”, “SPF TXT example”, “DNS has not propagated”. This page answers those. Check: A/AAAA on the right IP, MX preference on one provider, one SPF string, registrar NS matching the zone, TTL fit for a cutover. Compare the same query on two networks (wifi and mobile).

A CAA record limits which certificate authority may issue. With Let’s Encrypt, CAA must be empty or open to that CA or renewal fails. SRV records are required for SIP and some Microsoft services; without them the client misses the port. This tool lists common types; rare types stay in the panel.

Frequently asked questions

These are the queries people type for this tool. Answers match the visible text.

A row that maps a name to an IP, mail host or text proof. Types include A, AAAA, MX, NS, TXT and CNAME.

Enter the domain. The A row shows the IPv4 address. Multiple A rows can mean load balancing or a leftover IP.

The lowest preference is tried first. A wrong MX sends inbound mail to another host or nowhere.

About one TTL, usually 5–60 minutes. Some resolvers hold longer. Flush the local cache.

Two SPF TXT strings, a syntax error or a missing include. Merge into one record.

A CNAME cannot share the same name with other records. www as CNAME and apex as A is the usual, correct split.

It says which nameserver answers. If registrar NS and zone NS disagree, the site opens at random.

Use 300 during a cutover and 3600 when quiet. A constant 60 seconds burns quota and adds latency.

Only your own name or written authorisation. Bulk scanning is unlawful and unethical.

This page reads, it does not write. You or support apply changes in hosting or the registrar panel. In the office we lock MX and SSL with the cutover.
