Glue at parent nameservers 0/7

WARNING The parent servers are not providing glue for all your nameservers. This means that they are supplying the NS records (host.example.com), but not supplying the A records. That may cause some extra milliseconds in DNS. This will usually occur if your DNS servers are not in the same TLD as your domain

NS

Mismatched glue 7/7

Skip glue checking. Make sure the nameservers domain is good standing Check schlundtech.de

Nameservers A records 0/7

Some servers does not provide A records for nameservers.

missing A record(s) for (nsa7.schlundtech.de,nsb7.schlundtech.de,nsc7.schlundtech.de,nsd7.schlundtech.de) at nameserver 83.169.55.17
missing A record(s) for (nsd7.schlundtech.de,nsc7.schlundtech.de,nsb7.schlundtech.de,nsa7.schlundtech.de) at nameserver 74.208.254.27
missing A record(s) for (nsc7.schlundtech.de,nsa7.schlundtech.de,nsd7.schlundtech.de,nsb7.schlundtech.de) at nameserver 89.146.248.27

Nameservers report identical NS records 7/7

SUCCESS The NS records at all your nameservers are identical.

Nameservers respond 10/10

SUCCESS All of your nameservers listed at the parent nameservers responded.

Nameserver name validity 7/7

SUCCESS All of the NS records that your nameservers report are valid (no IPs or partial domain names).

Number of nameservers 5/5

SUCCESS You have 4 nameservers. You must have at least 2 nameservers (RFC2182 section 5 recommends at least 3 nameservers), and preferably no more than 7.

Lame nameservers 7/7

SUCCESS All the nameservers listed at the parent servers answer authoritatively for your domain.

Missing (stealth) nameservers 7/7

SUCCESS All your nameservers are also listed at the parent servers.

Root missing nameservers 7/7

SUCCESS All of the nameservers listed at the parent nameservers are also listed as NS records at your nameservers.

Nameservers on separate class C's 7/7

SOA

SOA record

SOA record is:
Hostmaster email
wolke.ixdreams.com
Serial
2019031700
Refresh
43200
Retry
7200
Expire
1209600
TTL
86400

Serial agreement 7/7

SUCCESS All your nameservers agree that your SOA serial number is 2019031700 That means that all your nameservers are using the same data.

SOA MNAME 3/3

SUCCESS SOA (Start of Authority) record states that your master (primary) name server is: nsa7.schlundtech.de That server is listed at the parent servers, which is correct.

Serial value 1/1

SUCCESS SOA serial number is: 2019031700 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 : 43200 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 : 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 1/1

SUCCESS SOA Expire time is : 1209600 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 : 86400 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.
