Well, the db.127.0.0.1 I had I changed back to db.127.0.0 as well as
0.0.127.in-addr.arpa.

I read some more again on the localhost since that evaded me since I
first started to use DNS servers.

If you have DNS & BIND, read pg. 67, the loopback address [3rd edition]

In short is says:

db.127.0.0:

0.0.127.in-addr.arpa	IN	NS	host.domain.tld.
0.0.127.in-addr.arpa	IN	NS	anotherhost.domain.tld.

1.0.0.127.in-addr.arpa	IN	PTR	localhost.

HTH, it helped me ;)
