I must clarify here IP addresses are fictitious, my bad i should have symbolized it properly. I just choose the digits came to my mind by repeating them in each block. The reason for doing telnet it to count the presence of valid application which listens to a certain port. Thats generally easy when doing only few ip addresses. The reason to scan blocks of IP is because its not clear which ip in network is available(up and on) i.e basically simplify the search. (a)If its valid system then would respond to telnet / port (b) if not then it would quit

In general its a reporting work should have been reported by some other way (but as circumstance required information which i was trying to get), as in a application which is present in many places largely separate remote networks it seems easy to telnet a certain port of a server staying within org network rather than connecting each GUI of the each app remotely etc and check manually
