SOA

SOA record

SOA record is:
Hostmaster email
hostmaster.europronet.ba
Serial
1528892239
Refresh
16384
Retry
2048
Expire
1048576
TTL
2560

Serial agreement 0/7

DANGER Some nameservers have a different soa serial number That can occur because of recent master update (slave have not loaded master zone yet) or the is a problem in DNS.
There is serial 1528892239 at nameserver(s) (80.65.162.100)
There is serial 1522408868 at nameserver(s) (217.199.128.10)

SOA MNAME 3/3

SUCCESS SOA (Start of Authority) record states that your master (primary) name server is: ns01.europronet.ba That server is listed at the parent servers, which is correct.

Serial value 1/1

SUCCESS SOA serial number is: 1528892239 This appears to be in the recommended format of YYYYMMDDnn, where 'nn' is the revision. This number must be incremented every time you make a DNS change.

Refresh value 1/1

SUCCESS SOA Retry interval is : 16384 seconds. This seems OK. (Values about 3600-7200 seconds is good if not using DNS NOTIFY; RFC1912 2.2 recommends a value between 1200 to 43200 seconds (20 minutes to 12 hours)). This value determines how often secondary/slave nameservers check with the master for updates.

Retry value 1/1

SUCCESS SOA Retry interval is : 2048 seconds. This seems OK. (Values about 120-7200 seconds is good). The retry value is the amount of time your secondary/slave nameservers will wait to contact the master nameserver again if the last attempt failed.

Expire value 1/1

SUCCESS SOA Expire time is : 1048576 seconds. This seems OK. (Values 604800 to 2419200 seconds (1-4 weeks) is good). RFC1912 suggests 2-4 weeks. This is how long a secondary/slave nameserver will wait before considering its DNS data stale if it can't reach the primary nameserver.

TTL value 1/1

SUCCESS SOA Expire time is : 2560 seconds. This seems OK. (about 300 to 86400 seconds or 5 min - 24 hours is good). RFC2308 suggests a value of 1-3 hours. This value used to determine the default (technically, minimum) TTL (time-to-live) for DNS entries, but now is used for negative caching.
