Looks okay to me.  Rather than using a web browser (which will tend to
lowercase the letters for you), use dig or some other direct tool:

dou@resolver:~$ dig @localhost ns1.nAno-HosT.CO.uk

; <<>> DiG 9.7.3 <<>> @localhost ns1.nAno-HosT.CO.uk

;; QUESTION SECTION:
;ns1.nAno-HosT.CO.uk.           IN      A

;; ANSWER SECTION:
ns1.nAno-HosT.CO.uk.    38400   IN      A       83.142.229.97

;; AUTHORITY SECTION:
nAno-HosT.CO.uk.        38400   IN      NS      ns2.nAno-HosT.CO.uk.
nAno-HosT.CO.uk.        38400   IN      NS      ns1.nAno-HosT.CO.uk.


and:


dou@resolver:~$ sudo tail /var/log/named/named.log
09-Mar-2012 19:38:18.910 client 127.0.0.1#48614: query:
ns1.nAno-HosT.CO.uk IN A + (127.0.0.1)

Best,
