Domain NS records |
Nameserver records returned by the parent servers are:
ns5.xxx.com. [] (NO GLUE) [TTL=1440]
ns6.xxx.com. [] (NO GLUE) [TTL=1440]
ns.irnic.ir was kind enough to give us that information. |
 |
TLD Parent Check |
Good. ns.irnic.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 ns.irnic.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 |
The parent nameserver ns.irnic.ir is not sending out GLUE for every nameservers listed, meaning he is sending out your nameservers host names without sending the A records of those nameservers. It's ok but you have to know that this will require an extra A lookup that can delay a little the connections to your site. This happens a lot if you have nameservers on different TLD (domain.com for example with nameserver ns.domain.org.) |
 |
Nameservers A records |
ERROR: Some of your DNS servers do not have A records at all. I could not find any A records for the following DNS servers:
ns5.xxx.com
ns6.xxx.com
You must have A records for all of your nameservers. |
| 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:
ns6.xxx.com ns5.xxx.com |
|
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:
ns5.xxx.com.
ns6.xxx.com. |
|
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.) |
