   CIDR looks good, that's what most software expect. Thanks! Sep 16, 2023 21:55:28 ipapi.is ***@***.***>:

   CIDR doesn't work for all networks.

   How would you represent the network

   1.2.3.4 - 1.2.3.7 in CIDR format?

   Kind regards, Nikolai

   Well 1.2.3.4/30? From .4 to .7. (Not caring about network and broadcast address).
   Maxmind use CIDR like this. If you then want network ranges, then you can convert with their tool.

   e.g:

   You are correct.

   How do you represent 1.2.3.1 - 1.2.3.7 in CIDR?

   Not possible with one CIDR address, you have to provide 3 CIDR ranges:

   1.2.3.1/32
   1.2.3.2/31
   1.2.3.4/30
   

   Conclusion:

   I will probably use the following format to represent IP ranges (Using integers):

   ipVersion,startIp,endIp
   4,1246803551,1246803551
   6,55838750780053364850524370207644844032,55838750780053364868971114281354395647
   

   Alternative, I can use the following format:

   ipVersion,startIp,endIp
   4,84.246.248.128,84.246.248.191
   4,84.246.248.192,84.246.248.255
   6,2606:54c0:7680:5330::,2606:54c0:7680:5330:ffff:ffff:ffff:ffff
   

   The problem with both of those formats is that they need considerably more space than CIDR format.

   while it takes up more space, it is a consistent 2 variables, rather than breaking up a range into potentially more than 2 cidrs. but i do think the format of choice should be consistent.
