Mail-OUT.Odessa.Net.
195.66.204.51

Sorry it should have been /24 not /28

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
