Parent

NS records at parent servers

ns1.theconnectingcompany.com
[These were obtained from ns2.nic.fr.]

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 theconnectingcompany.com

Nameservers A records 7/7

SUCCESS Nameservers do include corresponding A records when asked for your NS records. This ensures that your DNS servers know the A records corresponding to all your NS records.

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 0/5

DANGER You have less then 2 nameservers, that may cause downtime

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 0/7

DANGER There are nameservers not listed at your nameservers:
ns1.theconnectingcompany.com.

Nameservers on separate class C's 7/7

SUCCESS Nameservers are in a different networks.

public IPs 7/7

SUCCESS All of your NS records appear to use public IPs.

SOA

SOA record

SOA record is:
Hostmaster email
hostmaster.educatic.org.bo
Serial
1594713547
Refresh
10800
Retry
3600
Expire
604800
TTL
60

Serial agreement 7/7

SUCCESS All your nameservers agree that your SOA serial number is 1594713547 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: 208.91.197.91, but that server is not listed at the parent servers.

Serial value 1/1

SUCCESS SOA serial number is: 1594713547 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 : 10800 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 : 3600 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 : 604800 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 0/1

WARNING SOA Expire time is : 60 seconds. This seems too small. (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.
