dns110.ovh.net. [NO GLUE] [TTL=3600]
ns110.ovh.net. [NO GLUE] [TTL=3600]
WARNINGGlue at local nameserversOops! Your local nameservers don't return IP addresses (glue) along with your NS records! This isn't a fatal error but means an extra lookup needs to be performed increasing the load time to your site. You can fix this by adding A records for each of the nameservers listed above.
INFOSame glue at local and parent serversHrmm. Either the parent servers or your servers aren't returning GLUE for your nameservers. This means an extra lookup needs to be performed to get the IP's of your nameservers.

PASSEDCheck that all nameservers respondGood! All of your nameservers listed at the parent servers responded.

PASSEDNameservers are on different IP subnetsGood! All your nameservers are in separate class C (/24) subnets.
PASSEDNameservers have public IP'sGood! All your NS records have public IP addresses.
PASSEDNameservers allow TCP connectionsGood! We can establish a TCP connection with each of your nameservers on port 53. Whilst UDP is most commonly used for the DNS protocol, TCP connections are occasionally used.

Start of Authority (SOA) Tests
StatusTest CaseInformation
INFOSOA RecordYour Start of Authority (SOA) record is:

Primary nameserver: dns110.ovh.net.
Hostmaster E-mail address: tech.ovh.net.
Serial number: 2019022705
Refresh: 86400
Retry: 3600
Expire: 3600000
Minimum TTL: 300
PASSEDAll nameservers have same SOA serial numberGood! All your nameservers agree that your SOA serial number is 2019022705
PASSEDSOA primary nameserver listed at parentGood! The primary nameserver listed in your SOA record (dns110.ovh.net.) is listed at the parent servers!
PASSEDSOA serial number formatGood! Your SOA serial number (2019022705) appears to be in the recommended format (YYYYMMDDnn - where nn is the revision number).
PASSEDSOA Refresh valueGood! Your SOA Refresh value (86400) is within the recommended range of 1 hour (3600) to 1 day (86400).
PASSEDSOA Retry valueGood! Your SOA Retry value (3600) is within the recommended range of 5 minutes (300) to 4 hours (14400).
WARNINGSOA Expire valueOops! Your SOA Expire value (3600000) is outside of the recommended range of 1 week (604800) to 4 weeks (2419200). This value determines how long a secondary server may keep information before it is no longer authoritive. If this value is too low, the secondary servers may stop responding authoritatively too soon in the event of an outage on the primary nameserver. If it is too high, it may answer authortively for too long if it cannot reach the primary nameserver due network issues (e.g. firewall) making diagnosis difficult.
PASSEDSOA Minimum TTL valueGood! Your SOA Minimum TTL value (300) is within the recommended range of less than 3 days (259200).
