| Category | Status | Test name | Information |
|---|---|---|---|
| Parent |  |
Domain NS records | Nameserver records returned by the parent servers are: ns.behzad-m.net. ['216.157.145.10'] [TTL=172800] ns1.behzad-m.net. ['216.157.145.11'] [TTL=172800] b.gtld-servers.net was kind enough to give me that information. |
 |
TLD Parent Check | Good. b.gtld-servers.net, the parent server I interogated, 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 | Good. The parent server b.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 | Good. The parent nameserver sent GLUE, meaning he sent your nameservers as well as the IPs of your nameservers. Glue records are A records that are associated with NS records to provide "bootstrapping" information to the nameserver.(see RFC 1912 section 2.3) | |
|
Nameservers A records | Good. Every nameserver listed has A records. This is a must if you want to be found. | |
| NS |  |
NS records from your nameservers | NS records got from your nameservers listed at the parent NS are: ns1.behzad-m.net. ['216.157.145.11'] [TTL=86400] ns.behzad-m.net. ['216.157.145.10'] [TTL=86400] |
|
Recursive Queries | Good. Your nameservers (the ones reported by the parent server) do not report that they allow recursive queries for anyone. | |
|
Same Glue | The A records (the GLUE) got from the parent zone check are the same as the ones got from your nameservers. You have to make sure your parent server has the same NS records for your zone as you do according to the RFC. This tests only nameservers that are common at the parent and at your nameservers. If there are any missing or stealth nameservers you should see them below! | |
|
Glue for NS records | OK. When I asked your nameservers for your NS records they also returned the A records for the NS records. This is a good thing as it will spare an extra A lookup needed to find those A records. | |
|
Mismatched NS records | OK. The NS records at all your nameservers are identical. | |
|
DNS servers responded | Good. All nameservers listed at the parent server responded. | |
|
Multiple Nameservers | Good. You have multiple nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me. | |
|
Nameservers are lame | OK. All the nameservers listed at the parent servers answer authoritatively for your domain. | |
|
Missing nameservers reported by parent | OK. All NS records are the same at the parent and at your nameservers. | |
|
Missing nameservers reported by your nameservers | OK. All nameservers returned by the parent server b.gtld-servers.net 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. | |
 |
Different subnets | WARNING: Not all of your nameservers are in different subnets | |
|
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 like | |
 |
DNS servers allow TCP connection | OK. Seems all your DNS servers allow TCP connections. This is a good thing and usefull even if UDP connections are used by default. | |
|
Different autonomous systems | WARNING: Single point of failure | |
|
Stealth NS records sent | Ok. No stealth ns records are sent | |
| SOA | |
SOA record | The SOA record is: Primary nameserver: ns.behzad-m.net Hostmaster E-mail address: agabehzad.yahoo.com Serial #: 2004081579 Refresh: 10800 Retry: 3600 Expire: 604800 Default TTL: 86400 |
|
NSs have same SOA serial | OK. All your nameservers agree that your SOA serial number is 2004081579. | |
|
SOA MNAME entry | OK. ns.behzad-m.net That server is listed at the parent servers. | |
|
SOA Serial | Your SOA serial number is: 2004081579. This appears to be in the recommended format of YYYYMMDDnn. | |
|
SOA REFRESH | OK. Your SOA REFRESH interval is: 10800. That is OK | |
|
SOA RETRY | Your SOA RETRY value is: 3600. Looks ok | |
|
SOA EXPIRE | Your SOA EXPIRE number is: 604800.Looks ok | |
|
SOA MINIMUM TTL | Your SOA MINIMUM TTL is: 86400. This value was used to serve as a default TTL for records without a given TTL value and now is used for negative caching (indicates how long a resolver may cache the negative answer). Your value of 86400 is OK. | |
| MX | |
MX Records | Your MX records that were reported by your nameservers are: 10 mail1.behzad-m.net 216.157.145.21 [These are all the MX records that I found.] |
|
Different MX records at nameservers | Good. Looks like all your nameservers have the same set of MX records. This tests to see if there are any MX records not reported by all your nameservers and also MX records that have the same hostname but different IPs | |
|
MX name validity | Good. I did not detect any invalid hostnames for your MX records.> | |
|
MX IPs are public | OK. All of your MX records appear to use public IPs. | |
|
MX is not IP | OK. All of your MX records are host names. | |
|
Number of MX records | OK. Looks like you only have one MX record at your nameservers. You should be carefull about what you are doing since you have a single point of failure that can lead to mail being lost if the server is down for a long time. | |
|
Reverse MX A records (PTR) | Your reverse (PTR) record: 21.145.157.216.in-addr.arpa -> mail1.hsphere.cc You have reverse (PTR) records for all your IPs, that is a good thing. |

WWW A Record |
Your www.behzad-m.net A record is: www.behzad-m.net -> [216.157.136.192] |
