General DNS question pk <philip.kluss[ at ]gmail.com> 6/13/2007 1:59:48 PM This is a very simple question about DNS, but I just need some verification. If you're changing colocation facilities, are the nameservers registered with the registry (the ones returned by a 'whois' query) for that domain name what the DNS system uses to decide where to look for the authoritative DNS entry for that domain? I ask because we're moving 20 or so servers (with many more registered domain names attached) to a new facility and it seems very inconvenient to have to chase down the domain registry account for each of the domains that we're moving. I suppose this could be solved in the future by hosting our own DNS, but for the moment we're using the colocation facility's DNS servers as a "shadow DNS" [is there a more widely accepted name for that setup?]. I suppose it's not a huge rush to get things switched over to the new shadow DNS server since we'll strike a deal with the old host to continue providing that DNS server until we have everything switched over, but again, it's a hassle. I don't really know what I expect, of course moving 20 servers to a new data center is a hassle! How long does it take for the changes to the registry to become live in the DNS system? Thanks. pk

If you are asking about changes in Authoritative DNS in the public record at your registrar. it varies from registrar to registrar and TLD to TLD, some changes take place immediately, but because TTL varies (TTL is the time a record is held in cache) it may take 24 to 48 hours or more. -- Best regards, Kevin D.
