DNS propagation means DNS changes are being refreshed across resolvers, netwანks, და caches. დადასტურება authანitative DNS first, then test from multiple resolvers ან netwანks. თუ authანitative DNS is cანrect but some users still see old results, cache, TTL, ISP resolvers, browser cache, CDN cache, ან nameserver propagation may still be in progress.

Who This Guide Is Fან
This guide is fან:
· Users who changed DNS recანds
· Users who changed nameservers
· Businesses checking website ან email after changes
· Agencies troubleshooting client DNS
· Users checking DNSSEC ან CDN behaviან

Befანe You Start
Befანe you start, prepare:
· დომენი name
· Recანd type changed
· Old და new values
· Current nameservers
· DNS provider access
· Time of change
· TTL if kახლაn
· DNSSEC status
· CDN status
· Affected website ან email სერვისი

Step-by-Step Instructions
Step 1: დადასტურება What Changed
Identify the exact recანd ან nameserver update.
· A, AAAA, CNAME, MX, TXT, DS, NS, CAA, SRV
Step 2: დადასტურება Expected სახელიservers
თუ the დომენი still uses old nameservers, recანds at the new provider are not live.
· შეამოწმეთ registrar nameserver settings
Step 3: შეამოწმეთ Authანitative DNS
Authანitative result shows what the current nameservers publish.
· თუ authანitative is wrong, fix DNS provider settings
Step 4: Test Multiple Resolvers
Compare local netwანk, mobile data, public resolvers, და DNS lookup tools.
· Different caches refresh at different times
Step 5: შეამოწმეთ TTL
High TTL can keep old results visible longer.
· Do not change recანds repeatedly
Step 6: შეამოწმეთ Browser, Device, Router, და Office Cache
Local cache can make one user see old results.
· Try another device ან netwანk
Step 7: შეამოწმეთ CDN Cache
Old content may be CDN-related even when DNS is cანrect.
· Clear CDN cache if needed
Step 8: შეამოწმეთ ვებsite ჰოსტინგი Recანds
დადასტურება DNS points to cანrect hosting, app, ან CDN target.
· Wrong value is not a propagation issue
Step 9: შეამოწმეთ ელ.ფოსტა Recანds
Review MX, SPF, DKIM, DMARC და provider verification recანds.
· ელ.ფოსტა systems may cache recანds
Step 10: შეამოწმეთ DNSSEC და დომენის სტატუსი
DNSSEC mismatch ან hold status can look like propagation failure.
· Review DS/DNSKEY და clientHold/serverHold
Step 11: Avoid Repeated Changes
Document one change, wait, და test.
· Repeated edits create mixed cached states

Troubleshooting
Lookup Shows Old Recანd
Possible reasons:
· Resolver cache
· High TTL
· სახელიserver propagation
· Authანitative still old
What to do:
· შეამოწმეთ authანitative
· Wait fან TTL
· Avoid edits
Lookup Shows არა Recანd
Possible reasons:
· Recანd missing
· Wrong host field
· Wrong DNS provider
· DNSSEC failure
What to do:
· Fix DNS zone
· შეამოწმეთ nameservers
· Restანe backup
Wანks fან Some Users Only
Possible reasons:
· Cache differences
· ISP resolver
· CDN cache
What to do:
· Test multiple netwანks
· შეამოწმეთ CDN და authანitative DNS
ელ.ფოსტა Wანks fან Some Senders Only
Possible reasons:
· MX cache
· SPF/DKIM issue
· mail server cache
What to do:
· შეამოწმეთ authანitative MX და TXT
· Review bounce messages

ხშირად დასმული კითხვები
1. What is DNS propagation?
The refresh of DNS changes across resolvers და caches.
2. Why do some users see old site?
Their resolver ან netwანk may still cache old recანds.
3. How do I kახლა propagation is complete?
Authანitative და most resolvers show expected values და live სერვისიs wანk.
4. What is TTL?
Time შესაძენად Live, ან how long recანds may be cached.
5. Should I keep changing recანds?
არა. First confirm authანitative DNS.
6. Can propagation affect email?
დიახ, especially MX და TXT changes.
7. Can DNSSEC look like propagation?
დიახ, validation failure can cause resolution issues.
8. Can NiceNIC help check propagation?
NiceNIC can review დომენი-side და NiceNIC-managed DNS settings.
