IPv4 Custom list format
- 
 Hi, I need to add ranges of IP addresses in my IPv4 custom list. At present I have been adding each single IP on a single line. However lately have been getting spam from series of IP's. Is there anyway to add a range of IP's into the custom list. I can't seem to find the format of the lists. 
 e.g. 104.253.121.100-104.253.121.200Thanks.

 You may try 104.253.121.0/24. 
- 
 That would block the whole subnet though and I only want a range in the subnet 
- 
 dou you need traffic from this subnet? i wouldnt care.

 My tech guys 
 Use the notepad++ & m$ excel combo
 Means creating 100 and more lines
 If /24 doesn't do the trickAnother way round is set an alias in FW rules 
 For /24 and before that rule allow your Adress range
