You are right, I didn't catch the glue was supposed to be in .com wehere the NSes are, which are someone else's - doh - I expect that someone who providers nameservers takes care of gluing them appropriately, so it can work. > > My domain is lcrcomputer.com. if I use ns1 and ns2.lcrcomputer.com as > my name servers and do not have glue records for them in the .com root > servers, how is anyone going to find the name servers for my domain? > You are absolutely right, a small misreading in the scenario, my .org servers are of course glued in .org, if I had used all the NSes of the registrar (in .net, .com whatsoever), those of course would be glued in their corresponding parent zones. I expected that to be obvious and clear, as I said, I misread the scenario in the end and assumed that provided NSes are properly glued by their operators. > But in the example given, whoever owns example.com needs to create the > glue records by registering ns1 and ns2.example.com as name servers. > And if the owner of example.net does not make sure the name servers they > want to use are not registered, then they should not be wondering why > others will have trouble resolving example.net. > Agreed at some point we need glue and wherever a full delegation of a subzone is done, we need to have glue, no doubt ;-). > Lyle Giese > LCR Computer Services, Inc. > _______________________________________________ > Please visit https://lists.isc.org/mailman/listinfo/bind-users to > unsubscribe from this list > > bind-users mailing list > bind-users@lists.isc.org > https://lists.isc.org/mailman/listinfo/bind-users > Regards -Sven _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
