Step-by-step guide

Open the DNS checker. Go to enterno.io/en/dns.
Enter a domain. Without www. or scheme (https://). Example: enterno.io or subdomain.example.com.
Pick record types. Default: all. You can specify individual ones: A, MX, TXT for a quick check.
Click "Check". Result: a table of every found record with TTL and MX priority.
Check propagation. For DNS change monitoring, use the DNS Propagation Checker — from 15+ global resolvers.

What are DNS Records?

DNS (Domain Name System) translates domain names into IP addresses. DNS records are instructions that define where to route traffic, email, and how to verify domainownership.

Common Mistakes

❌

Missing SPF recordWithout SPF, emails may land in spam. Add a v=spf1 TXT record.

❌

Single NS serverIf the only NS fails, the domain becomes unreachable. Use at least 2 NS servers.

❌

CNAME conflicting with other recordsCNAME cannot coexist with MX or TXT on the same name — this violates RFC.

❌

TTL set too highWith 86400s TTL, DNS changes take a full day. Lower TTL to 300 before migrations.

❌

Missing PTR recordMail servers check PTR. Without it, emails may be rejected.

Best Practices

✓

Set up SPF + DKIM + DMARCThe trio of records that protects your email from spoofing and improves deliverability.

✓

Use 2+ NS serversDistribute NS servers across different networks for redundancy.

✓

Lower TTL before migrationSet TTL to 300 at least 24-48 hours before an IP change for fast propagation.

✓

Verify DNS after changesAfter updating records, confirm changes propagated correctly and no errors remain.

✓

Add a CAA recordCAA restricts which Certificate Authorities can issue SSL certificates for your domain.
