Domain NS records |
Nameserver records returned by the parent servers are:
name1.xxx.ir. ['176.9.xxx.109'] [TTL=1440]
name2.xxx.ir. ['176.9.xxx.109'] [TTL=1440]
a.nic.ir was kind enough to give us that information. |
|
TLD Parent Check |
Good. a.nic.ir, the parent server I interrogated, 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 a.nic.ir 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:
Oups! I could not get any nameservers from your nameservers (the ones listed at the parent server). Please verify that they are not lame nameservers and are configured properly. |
|
Recursive Queries |
Good. Your nameservers (the ones reported by the parent server) do not report that they allow recursive queries for anyone. |
|
Same Glue |
Hmm,I do not consider this to be an error yet, since I did not detect any nameservers at your nameservers. |
|
Glue for NS records |
OK. Your nameservers (the ones reported by the parent server) have no ideea who your nameservers are so this will be a pass since you already have a lot of errors! |
 |
Mismatched NS records |
WARNING: One or more of your nameservers did not return any of your NS records. |
|
DNS servers responded |
ERROR: One or more of your nameservers did not respond:
The ones that did not respond are:
176.9.xxx.109 |
|
Name of nameservers are valid |
OK. The nameservers reported by the parent send out nothing as shown above. I can't check nothing so it's a green! |
|
Multiple Nameservers |
ERROR: Looks like you have less than 2 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 |
You should already know that your NS records at your nameservers are missing, so here it is again:
name1.xxx.ir.
name2.xxx.ir. |
|
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 |
OK. Looks like you have nameservers on 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 useful even if UDP connections are used by default. |
|
Different autonomous systems |
OK. It seems you are safe from a single point of failure. You must be careful about this and try to have nameservers on different locations as it can prevent a lot of problems if one nameserver goes down. |
|
Stealth NS records sent |
Ok. No stealth ns records are sent |
| SOA |
|
SOA record |
No valid SOA record came back! |
| MX |
|
MX Records |
Oh well, I did not detect any MX records so you probably don't have any and if you know you should have then they may be missing at your nameservers! |
| WWW |
|
WWW A Record |
ERROR: I could not get any A records for www.xxx.ir!
(I only do a cache request, if you recently added a WWW A record, it might not show up here.) |
