All ntop does is use the standard gethostbyname() function. There are some
knowledge base articles about it - fixes in SP2.
Now, it should just return the same thing (see note below from
gethostbyname() man page), but perhaps they are being clever??
Anyway, try
1) nslookup on the numeric address
2) use the name in the -g parameter (or both)
and let us know...

man gethostbyname
...
The name argument to gethostbyname is a character string containing an
Internet hostname or an Internet address in standard dot notation (see
inet(3N)). If the name contains no dot, and if the environment
variable
HOSTALIASES contains the name of an alias file, the alias file is first
searched for an alias matching the input name. See hostname(5) for the
alias file format. The addr argument to gethostbyaddr points to a
buffer
containing a 32-bit Internet host address in network byte order.
addrlen
contains the address length in bytes; it should be set to sizeof(struct
in_addr). type specifies the address family and should be set to
AF_INET.
