What does the following mean.
smtp.example.com. A 192.167.1.25
mx.example.com. A 192.168.1.19
example.com. MX mx.example.com.
example.com. TXT "v=spf1 a:smtp.example.com/28 mx -all"
Does it mean 192.167.1.25 192.168.1.19-192.168.2.18
OR DOES IT MEAN 192.167.1.25 192.168.1.0-192.168.1.255
Neither one. It allows emails from 192.167.1.25/28 and 192.168.1.19.
The 192.167.1.25/28 part means 192.167.1.16-192.167.1.31.
Notice I am listing both the range and the mx single ip.
This is not a problem.
The answer is that it has 2 different meanings and the answer depends on who
is giving the answer.
I don't really understand how you could come to your two meanings. They
are not right either way you see it.
