Is there a subcription list to announce new updates to the different country or continent list?

Your site is awesome and if user could be notified of changes to the lists, that would be great.

thank you.

I want to allow all traffic from Telecom Italia. How can I get a listing of all IP address blocks registered to them? Thanks! Cheers,

You made a statement, but you failed to include the relevance or a question.

If your concern is defeating brute force attacks against an FTP server one of the simpler security methods you should try is to limit FTP access to a select few IP addresses and by default deny everyone else. Dictionary attacks will not work if they never get the opportunity to try any credentials.

Script was performing Dictionnary Brute Force Attack in order to gain access to FTP server.

In a /18 network the first 18 bits are used for the network ID. The remaining 14 bits are used for the host ID. A CIDR /18 network has 16,384 addresses available (including the two reserved addresses). 209.109.96.0/18 is made up of two /19 networks: 209.109.96.0/19, 209.109.128.0/19; each has 8,192 addresses.

Convert 209.109.96.0 into decimal: 3513606144
Convert 209.109.159.255 into decimal: 3513622527

Subtract the top number from the bottom number and add 1 to the total. This gives us 16,384 addresses (zero counts as 1) or a CIDR /18.

The network range you mentioned: 209.109.64.0 – 209.109.127.255, is actually a CIDR /19. A /19 has 8,192 addresses.

I might be wrong, but it appears to me that 209.109.96.0/18, which your web site shows as 209.109.96.0 – 209.109.159.255 would actually be a range of 209.109.64.0 – 209.109.127.255 . There are several entries in the United States table with this .96.0/18 . Please explain.
