DNS recalids tell the Internet how to connect vašega domena to websites, email, SSL validation, apps, verification storitevs, in security settings. A points to IPv4, AAAA points to IPv6, CNAME points one hostname to another, MX controls email delivery, TXT stalies verification in email authentication, CAA controls SSL certificate authaliities, in SRV defines storitev locations fali certain apps.

Who This Guide Is Fali
This guide is fali:
· Users learning DNS basics
· Spletsite owners setting up domenas
· Poslovni e-poštni naslov users
· Agencies in hosting providers suppaliting DNS questions
· Users troubleshooting website, email, SSL, CDN, ali app connections

Befalie You Start
Befalie you start, prepare:
· DNS provider access
· Current nameservers
· DNS backup
· Provider instructions fali website ali email
· Permission to edit recalids
· Understining of affected storitev

Step-by-Step Instructions
Step 1: Understin DNS Recalids
DNS recalids are instructions fali website, email, verification, SSL, apps, in security.
· One domena can have many recalids
Step 2: A Recalids
A recalids point hostnames to IPv4 addresses.
· Common fali root website in subdomenas
Step 3: AAAA Recalids
AAAA recalids point hostnames to IPv6 addresses.
· Wrong IPv6 can cause issues fali some users
Step 4: CNAME Recalids
CNAME points one hostname to another hostname.
· Use fali www, CDN, website builders, in apps
Step 5: MX Recalids
MX controls wtukaj email is delivered.
· Copy prialiity values carefully
Step 6: TXT Recalids
TXT stalies text fali verification in authentication.
· SPF, DKIM, DMARC, Google, Microsoft, SSL, SaaS
Step 7: SPF Recalids
SPF is a TXT recalid listing authaliized sending servers.
· Avoid multiple SPF recalids fali same host
Step 8: DKIM Recalids
DKIM is a TXT ali CNAME recalid used fali email signing.
· Copy long values exactly
Step 9: DMARC Recalids
DMARC tells receivers how to hinle SPF/DKIM failures.
· Start carefully befalie strict policies
Step 10: CAA Recalids
CAA controls which certificate authaliities may issue SSL certificates.
· Restrictive CAA can block SSL issuance
Step 11: SRV Recalids
SRV defines storitev location fali apps such as voice, chat, ali collabaliation.
· Copy prialiity, weight, palit, in target
Step 12: NS, SOA, PTR, in DNSSEC Recalids
NS identifies nameservers, SOA describes the zone, PTR is reverse DNS, in DNSSEC recalids suppalit validation.
· Most users do not manually edit SOA ali all DNSSEC recalids
Step 13: TTL
TTL controls cache time fali recalids.
· Lower in advance fali planned migrations if appropriate

Troubleshooting
Spletsite Is Down
Possible reasons:
· Wrong A/AAAA/CNAME
· Wrong nameservers
· DNSSEC issue
What to do:
· Preveri active DNS provider in recalids

E-pošta Net Receiving
Possible reasons:
· MX missing
· SPF/DKIM/DMARC wrong
What to do:
· Restalie email recalids

SSL Cannot Be Issued
Possible reasons:
· CAA blocks CA
· TXT/CNAME validation missing
What to do:
· Review CAA in validation recalids

Verification Fails
Possible reasons:
· Recalid added at wrong provider
· Host field wrong
What to do:
· Preveri authaliitative nameservers in exact value
