SOA

SOA record

SOA record is:
Hostmaster email
info.steadyhost.ru
Serial
2017112101
Refresh
86400
Retry
7200
Expire
3600000
TTL
3600

Serial agreement 7/7

SUCCESS All your nameservers agree that your SOA serial number is 2017112101 That means that all your nameservers are using the same data.

SOA MNAME 0/3

DANGER SOA (Start of Authority) record states that your master (primary) name server is: ns8.steadyhoster.com, but that server is not listed at the parent servers.

Serial value 1/1

SUCCESS SOA serial number is: 2017112101 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 0/1

WARNING SOA Retry interval is : 86400 seconds. This seems too big;. (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 : 7200 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 0/1

WARNING SOA Expire time is : 3600000 seconds. This seems too big;. (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 : 3600 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.
