Range of IP addresses in "allow hosts"?

[Owen L. Magee]

Is there any easy way to specify a range of IP addresses in "allow
hosts"?  For instance what if I wanted to specify 1.2.3.112 - 1.2.3.180?
Do I just have to specify them individually in "allow hosts", and if so,
is there any limit on how long that line can be?

(I tried to see if this had been discussed before in the archives on the
Samba home page, but it appears to be broken at the moment.)

Thanks...
