PARENT0.0 ms |
Domain NS records |
Nameserver records returned by the parent servers are:
a.ns.whatsapp.net [129.134.30.12, 2a03:2880:f0fc:c:face:b00c:0:35] (NO GLUE) [TTL=172800] b.ns.whatsapp.net [129.134.31.12, 2a03:2880:f0fd:c:face:b00c:0:35] (NO GLUE) [TTL=172800] c.ns.whatsapp.net [185.89.218.12, 2a03:2880:f1fc:c:face:b00c:0:35] (NO GLUE) [TTL=172800] d.ns.whatsapp.net [185.89.219.12, 2a03:2880:f1fd:c:face:b00c:0:35] (NO GLUE) [TTL=172800] j.gtld-servers.net was kind enough to give us that information. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| TLD Parent Check |
j.gtld-servers.net has information for your TLD.
This is a good thing as there are some other domain extensions like "co.us" for example that are missing a direct check. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Your nameservers are listed |
j.gtld-servers.net has your nameservers listed.
This is a must if you want to be found as anyone that does not know your DNS servers will first ask the parent nameservers. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| DNS Parent sent Glue |
0 of 4 nameservers sent GLUE.
The parent nameserver a.gtld-servers.net is not sending out GLUE for every nameserver listed, meaning it is sending your nameserver hostnames without their corresponding A records. This is acceptable, but it requires an extra A record lookup, which may slightly delay DNS resolution. This often occurs when nameservers are on a different TLD (e.g., domain.com with nameserver ns.otherdomain.com). |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Nameservers A records |
Every nameserver listed has A records.
This is a must if you want to be found. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
NS2757.7 ms |
NS records from your NameServers |
NS records returned by the currently delegated nameservers are:
All NS records have the same TTL: 86400 seconds. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Public Resolver |
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Mismatched NS records |
The NS records at all your nameservers are identical to those listed by the parent.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| DNS servers responded |
All nameservers listed at the parent server responded.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Name of nameservers are valid |
All of the NS records that your nameservers report seem valid.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Multiple Nameservers |
You have 4 nameservers. According to RFC2182 section 5, this is recommended.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Missing nameservers reported by parent |
All NS records are the same at the parent and at your nameservers.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Missing nameservers reported by your nameservers |
All nameservers returned by the parent server are the same as the ones reported by your nameservers.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Domain CNAMEs |
OK. RFC1912 2.4 and RFC2181 10.3 state that there should be no CNAMEs if an NS (or any other) record is present.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| NSs CNAME check |
OK. RFC1912 2.4 and RFC2181 10.3 state that there should be no CNAMEs if an NS (or any other) record is present.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Different subnets |
You have nameservers on different subnets.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Recursive Queries |
a.ns.whatsapp.net → ✅ does not allow recursion (good)
c.ns.whatsapp.net → ✅ does not allow recursion (good) b.ns.whatsapp.net → ✅ does not allow recursion (good) d.ns.whatsapp.net → ✅ does not allow recursion (good) |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Same Glue |
Mismatch between parent GLUE and zone A records:
a.ns.whatsapp.net → Parent: 129.134.30.12, 2a03:2880:f0fc:c:face:b00c:0:35 | Zone: 129.134.30.12 b.ns.whatsapp.net → Parent: 129.134.31.12, 2a03:2880:f0fd:c:face:b00c:0:35 | Zone: 129.134.31.12 c.ns.whatsapp.net → Parent: 185.89.218.12, 2a03:2880:f1fc:c:face:b00c:0:35 | Zone: 185.89.218.12 d.ns.whatsapp.net → Parent: 185.89.219.12, 2a03:2880:f1fd:c:face:b00c:0:35 | Zone: 185.89.219.12 Make sure both match to comply with DNS best practices. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| NS Self-IP Consistency |
All nameservers return consistent IP addresses with what they declare in the zone.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Glue for NS records |
All your NS servers sent GLUE when asked.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Nameservers are lame |
All the nameservers listed at the parent servers answer authoritatively for your domain.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| IPs of nameservers are public |
Ok. Looks like the IP addresses of your nameservers are public.
This is a good thing because it will prevent DNS delays and other problems. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| DNS servers allow TCP connection |
OK. Seems all your DNS servers allow TCP connections.
This is a good thing and useful even if UDP connections are used by default. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Different autonomous systems |
All authoritative name servers appear to be in the same autonomous system: AS32934.
Using a single AS reduces resiliency and increases the blast radius of network incidents. Consider hosting your NS records across multiple autonomous systems. WARNING: Single point of failure. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Stealth NS records sent |
Ok. No stealth NS records are sent
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
DNSSEC150.1 ms |
Zone signed |
DNSSEC: Unsigned
No RRSIG record found. The zone is not signed with DNSSEC. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| DNSKEY records |
No DNSKEY records found.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| DS record in parent |
No DS record found in the parent zone.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| NSEC/NSEC3 record |
No NSEC or NSEC3 record found when querying a non-existent subdomain.
This may indicate a misconfiguration or lack of proper DNSSEC denial-of-existence support. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
SOA0.1 ms |
SOA Record |
The SOA (Start of Authority) record is:
Primary nameserver: a.ns.whatsapp.net Hostmaster E-mail address: dns@whatsapp@net Serial #: 4207849484 Refresh: 14400 Retry: 1800 Expire: 604800 Default TTL: 300 |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| NSs have same SOA serial |
OK. All your nameservers agree that your SOA serial number is 4207849484.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| SOA MNAME entry |
OK. a.ns.whatsapp.net is listed at the parent servers.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| SOA Serial |
Your SOA serial number is: 4207849484. This appears to follow the recommended YYYYMMDDnn format.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| SOA REFRESH |
Your SOA REFRESH interval is: 14400. OK.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| SOA RETRY |
Your SOA RETRY value is: 1800. OK.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| SOA EXPIRE |
Your SOA EXPIRE number is: 604800. Looks OK.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| SOA MINIMUM TTL |
Minimum TTL is low (300). Recommended: 1h+ (3600).
A low minimum TTL results in more frequent DNS queries, which can increase server load. A higher value improves cache efficiency. |
