Without glue, how do DNS servers know the ip of nameservers? ns2 namecity com ['84 22 161 171'] (NO GLUE) [TTL=172800] And on the website intoDNS, there is this warning: The parent nameserver ns1 nic uk 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
How do I fix no GLUE problem with DNS lookups? Without a glue record, if a request were made for the A records www example com, a name server serving "com" would return the NS record for example com as ns example com (not an IP), and the original request would have no way of being resolved, because any further attempt to resolve ns example com would merely refer back to ns example com
domain name system - What is a glue record? - Server Fault To break the dependency, the nameserver for the org top level domain includes glue along with the delegation for example org The glue records are address records that provide IP addresses for ns1 example org
domain name system - Inconsistent Glue Records - Server Fault In particular, it appears that the glue records setup at the TLD ( host in this case) has glue records setup for our 4 nameservers but 2 of their NIC servers do not have an IP address assigned In particular, host has 4 NIC servers (a nic host - d nic host) and it appears that only a nic host and b nic host has IP addresses assigned to our 4
What is the difference between the NS records and the glue records? Some resolvers will use the glue records without double-checking and some will query the NS records from the authoritative name servers (the ones provided in the glue records) to make sure they are actually correct I know from experience that PowerDNS is in the former group and bind9 is in the latter I have no experience with any other resolvers
domain name system - How to test DNS glue record? - Server Fault Hello I have just set up a DNS server for my domain example org with 2 name servers ns1 example org and ns2 example org I have attempted to set up a glue record for ns1 and ns2 at my registrar It
Are Glue records in DNS used only by nameservers of . . . - Server Fault That should be enough by itself, but I could also define a glue record for it: ns1 contoso com IN A 203 0 113 1 This would cause my nameserver to include 203 0 113 1 in the referrals for ns1 contoso com as glue My nameservers aren't responsible for contoso com, and no sane nameserver on the internet is going to store that glue record in cache
When are DNS glue (or host) records needed? - Server Fault In real life I've learned that some domain providers need glue records even when dns is not the one authoritative for domain that it is subdomain of and domain being subject is not that domain Like they need glue records for ns4 example com to add dns for somedomain com when ns4 example com does not serve example com (ns1 and ns2 does) –
How do DNS servers respond to missing glue records? Any glue encountered along the way will be followed as normal I won't quote RFC 1034 §4 3 2 here as it's somewhat silly to restate basic operation fundamentals In short, glue is only mandatory where both the standards or the policy of specific registrars (or registries) require it The latter requiring it is not necessarily an indication of
Glue record limitations for authoritative nameservers Again, there are no glues involved here as your nameservers names are not using the domains (site-net example) you use them for Every domain has ns1 and ns2 for its nameservers Therefore, I created glue records for each Note that this means there are no glue records for ns3 and ns4 Glues are needed ONLY if the nameserver is used
