The tools that transfer these zonelets rely on this extra piece of
information in the TXT record for consistency checks. Similarly,
AfriNIC, ARIN and APNIC also generate zones for their /8 allocations
with records named "afrinic", "arin" and "apnic".
The e164.arpa zone does not really need this "ripe" record in it,
since
it is not shared among the registries in any way. However, because the
e164.arpa zone is generated automatically from the RIPE Database by
the
same tools, it automatically receives this extra name. Currently,
there
is no way to stop the zone receiving this extra entry. But it has no
negative effect on the zone or on ENUM operations.
