One major block of addresses reserved for special purposes is the IPv4 experimental address range 240.0.0.0 to 255.255.255.254. Currently, they cannot be used in IPv4 networks. However, these addresses could be used for research or experimentation.
IPv4 private addresses:Class A addresses in the range 10.0.0.0 to 10.255.255.255Class B addresses in the range 172.16.0.0 to 172.31.255.255Class C addresses in the range 192.168.0.0 to 192.168.255.255IPv6 private addresses:All IPv6 addresses with the prefix FC00::/7 are regarded as private.
IP addresses are divided into five IP classes:IP address class AIP address class BIP address class CIP address class DIP address class E
In Internet Protocol version 4 (IPv4), an address beginning with a binary 1110. Class D addresses are reserved for multicast applications.
There are 2^24 host in class A but (2^24)-2 hosts are valid since the first and last address are reserved .

IPv4 private addresses:Class A addresses in the range 10.0.0.0 to 10.255.255.255Class B addresses in the range 172.16.0.0 to 172.31.255.255Class C addresses in the range 192.168.0.0 to 192.168.255.255IPv6 private addresses:All IPv6 addresses with the prefix FC00::/7 are regarded as private.
"The RFC 1918 private network numbers are 10.0.0.0, Class Bs between 172.16.0.0 and 172.31.0.0 inclusive, and all Class C networks that begin with 192.168. All addresses that begin with 127 are reserved, but not as valid private IP addresses."
The company decides what addresses to use for the local network; the reserved address ranges, recommended for private networks, are:Class A: 10.0.0.0 - 10.255.255.255Class B: 172.16.0.0 - 172.31.255.255Class C: 192.168.0.0 - 192.168.255.255
A class D network is reserved for multi-casting. The class E series of network addresses are reserved for experimental purposes. 240 - 255 are reserved for class E addresses.
The internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets (local networks): 10.0.0.0 - 10.255.255.255172.16.0.0 - 172.31.255.255192.168.0.0 - 192.168.255.255Also, IP addresses in the range of 169.254.0.0 -169.254.255.255 are reserved for Automatic Private IP Addressing. These IP's should not be used on the Internet. I usually use 192.168.0.1, 192.168.0.2, etc. and a subnet mask of 255.255.255.0 when assigning static IP addresses to computers on a small Local Area Networks (LANs). If a DHCP server is also on the LAN it's scope (range of IP addresses that it can assign to computers on the LAN set to obtain their IP addresses automatically) should be adjusted so it does not interfere with locally assigned static IP addresses.
The globally scoped multicast addresses range from 224.0.1.0 to 238.255.255.255. These addresses are reserved for multicast communications across the internet.

The problem with your IP address lies in the first octet. 127.0.0.1 addresses are reserved for loopback addresses.
254 - a class C subnet uses 8 bits for the hosts and 0 and 255 are reserved.
