You need to make sure that these nameservers are working.If they are not working ok, you may have problems! All the nameservers listed at the parent servers answer authoritatively for your domain.įAIL: The following nameservers are listed at your nameservers as nameservers for your domain, but are not listed at the parent nameservers (see RFC2181 5.4.1). According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. All of the NS records that your nameservers report seem valid. All nameservers listed at the parent server responded. The NS records at all your nameservers are identical. You can fix this for example by adding A records to your nameservers for the zones listed above. INFO: GLUE was not sent when I asked your nameservers for your NS records.This is ok but you should know that in this case an extra A record lookup is required in order to get the IPs of your NS records. If there are any missing or stealth nameservers you should see them below! This tests only nameservers that are common at the parent and at 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. The A records (the GLUE) got from the parent zone check are the same as the ones got from your nameservers. You should not have nameservers that allow recursive queries as this will allow almost anyone to use your nameservers and can cause problems. It may be that I am wrong but the chances of that are low. I could use the nameservers listed below to performe recursive queries. NS records got from your nameservers listed at the parent NS are: Provide "bootstrapping" information to the nameserver.(see RFC 1912 section 2.3) Glue records are A records that are associated with NS records to The parent nameserver sent GLUE, meaning he sent your nameservers as well as the IPs of your nameservers. 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. The parent server a. has your nameservers listed. This is a good thing as there are some other domain extensions like "co.us" for example that are missing a direct check. Good. a., the parent server I interrogated, has information for your TLD. Nameserver records returned by the parent servers are:Ī. was kind enough to give us that information.
