Parent Info Domain NS records Nameserver records returned by the parent servers are:

ns1.dreamhost.com   ['66.33.206.206']   [TTL=172800]
ns2.dreamhost.com   ['208.97.182.10']   [TTL=172800]
ns3.dreamhost.com   ['66.33.216.216']   [TTL=172800]

m.gtld-servers.net. was kind enough to give us that information.
Pass TLD Parent Check Good. m.gtld-servers.net., the parent server I interrogated, has information for your TLD.
Pass Your nameservers are listed Good. The parent server m.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 Info 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.

Pass Recursive Queries Good. Your nameservers (the ones reported by the parent server) do not report that they allow recursive queries for anyone.
Pass Same Glue Hmm,I do not consider this to be an error yet, since I did not detect any nameservers at your nameservers
Pass 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!
Error Mismatched NS records OK. The NS records at all your nameservers are identical.
Error DNS servers responded Good. All nameservers listed at the parent server responded.
Pass Name of nameservers are valid OK. All of the NS records that your nameservers report seem valid.
Error Multiple Nameservers Good. You have multiple nameserversAccording to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me.
Pass Nameservers are lame Following nameservers listed at the parent servers does not answer authoritatively for your domain. ns1.dreamhost.com
ns2.dreamhost.com
ns3.dreamhost.com
Pass Missing nameservers reported by parent OK. All NS records are the same at the parent and at your nameservers.
Pass Missing nameservers reported by your nameservers ERROR: One or more of the nameservers listed at the parent servers are not listed as NS records at your nameservers. The problem NS records are:

ns1.dreamhost.com
ns2.dreamhost.com
ns3.dreamhost.com
This is listed as an ERROR because there are some cases where nasty problems can occur (if the TTLs vary from the NS records at the root servers and the NS records point to your own domain, for example).
Pass 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.
Pass 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.
Pass Different subnets OK. Looks like you have nameservers on different subnets!
Pass 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
Pass 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.
Pass 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.
Pass Stealth NS records sent Ok. No stealth ns records are sent
SOA SOA record No valid SOA record came back!
MX Info 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 Info WWW A Record Your www.shop4korea.com A record is:
->[]

Pass IPs are public OK. All of your WWW IPs appear to be public IPs.
Pass WWW CNAME OK. No CNAME
