Once you have learned to write an coherent question, one might be able to 
help you.

Please also learn to quote.  The attribution lines are relevant as a posting 
replied to now can and will expire later.

No.  First of all, nation and country are different subjects.  A country can 
have, and I daresay by now most countries do have, inhabitants from several 
nations.  There is also the increasingly likely possibility for a person to 
have multiple nationalities.

Second, IP address ranges are allocated to *Regional* Internet Registries 
(RIRs), which then allocate them for Local Internet Registries (LIRs).  LIRs 
include Internet service providers, enterprises, or academic institutions:

<https://en.wikipedia.org/wiki/IPv4#Allocation>
<https://en.wikipedia.org/wiki/IPv6_address#IPv6_address_space>

>  101.xxx.xxx.xxx  to 150.xxx.xxx.xxx     all ip nation  B
>  151.xxx.xxx.xxx  to 200.xxx.xxx.xxx     all ip nation  C

This cannot be correct because several address ranges within those ranges 
are reserved for special use already:

No.  Why do you want to determine the nation/country?
