Quick question about SPF records across an IP address range.

Let's say I have a range of IP addresses that I want to allow - say it's:

xx.xx.xxx.135 through
xx.xx.xxx.184

What would the syntax for that be?

Thanks!

Should be: ip4:x.x.x.x/nn so the cidr notation. Have a look at: http://www.openspf.org/SPF_Record_Syntax

I read that - and that's what confused me.  For example - it says:

"v=spf1 ip4:192.168.0.1/16 -all"
Allow any IP address between 192.168.0.1 and 192.168.255.255"

Which isn't exactly what I'm looking for.

Let's say I just want:

192.168.0.1 through
192.168.0.16

?
