Before contacting the registrar, you will have to add
&:198.41.0.4:a.root-servers.net &:128.9.0.107:b.root-servers.net &:192.33.4.12:c.root-servers.net &:128.8.10.90:d.root-servers.net &:192.203.230.10:e.root-servers.net &:192.5.5.241:f.root-servers.net &:192.112.36.4:g.root-servers.net &:128.63.2.53:h.root-servers.net &:192.36.148.17:i.root-servers.net &:192.58.128.30:j.root-servers.net &:193.0.14.129:k.root-servers.net &:198.32.64.12:l.root-servers.net &:202.12.27.33:m.root-servers.net .localhost .1.0.0.127.in-addr.arpa =localhost:127.0.0.1to /service/tinydns/root/data. This is necessary because the .fr registrar refuses to delegate to a server that does not have this information. (Reported May 2001.) This is bad practice, because it forces you to keep track of information that's only necessary for a cache, even if you aren't running a cache.
