FTR, that list of IP addresses includes the servers (DNS, POP3, and SMTP) used by VSNL, but it apparently does not include other IPs assigned to VSNL customers while they are connected to the web.
Whois lookups indicate that VSNL also controls 219.64.0.0 - 219.65.255.255 , 203.197.0.0 - 203.197.255.255 , and 203.199.0.0 - 203.199.255.255 , for example.
