NS records at parent servers
ns1.webhost.pro
ns2.webhost.pro
ns3.webhost.pro
[These were obtained from a.gtld-servers.net.]
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 webhost.pro
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
5/5
SUCCESS
You have 3 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
0/7
DANGER
There are nameservers not listed at the parent servers:
ns1.dwhs.net.
ns2.dwhs.net.
ns3.dwhs.net.
Root missing nameservers
0/7
DANGER
There are nameservers not listed at your nameservers:
SUCCESS
All of your NS records appear to use public IPs.
SOA
SOA record
SOA record is:
Hostmaster email
logs.dwhs.net
Serial
2018121800
Refresh
3600
Retry
7200
Expire
1209600
TTL
86400
Serial agreement
7/7
SUCCESS
All your nameservers agree that your SOA serial number is 2018121800 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: ns1.dwhs.net, but that server is not listed at the parent servers.
Serial value
1/1
SUCCESS
SOA serial number is: 2018121800 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 : 3600 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.
