Parent

NS records at parent servers

sdns1.ovh.ca
vps136710.vps.ovh.ca
[These were obtained from a0.info.afilias-nst.info.]

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 ovh.ca Check vps.ovh.ca

Nameservers A records 0/7

Some servers does not provide A records for nameservers.
missing A record(s) for (sdns1.ovh.ca,vps136710.vps.ovh.ca) at nameserver 158.69.208.21

Nameservers report identical NS records 0/7

The NS records at your nameservers are different
At (8.33.137.137) there are nameservers:
At (158.69.208.21) there are nameservers: sdns1.ovh.ca. vps136710.vps.ovh.ca.

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 2/5

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

Lame nameservers 0/7

Lame nameservers:
8.33.137.137

Missing (stealth) nameservers 7/7

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

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

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
Serial
Refresh
Retry
Expire
TTL

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 at nameserver(s) (8.33.137.137)
There is serial 2017070404 at nameserver(s) (158.69.208.21)

SOA MNAME 0/3

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

Serial value 0/1

WARNING SOA serial number is: This not 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 : seconds. This seems too small. (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 0/1

WARNING SOA Retry interval is : seconds. This seems too small. (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 : seconds. This seems too small. (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 : 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.
