The 127.0.0.0/8 is a CDIR netblock reserved by IANA and it's called Loopback. This traffic is routed by kernel to a a special network adapter called loopback adapter. It never hits the OSI Model Layer 1, as any local traffic. For most all OS data travels across the network kernel services until the IP stack.
127.0.0.0 to 127.255.255.255 is mapped to loop back address and you should get valid reply if you ping an IP address in this range from your computer. 10:41 AM Anonymous said… > bootes:/root # route -n > Kernel IP routing table > Destination Gateway Genmask Flags Metric Ref Use Iface > 127.0.0.1 0.0.0.0 255.255.255.255 UH 0 0 0 lo I'm connecting to my server (Centos 7) with ssh and I try to ping to localhost: ping 127.0.0.1 but doesn't work: ping 127.0.0.1 PING 127.0.0.1 (127.0.0.1) 56(84) bytes of data. ^C --- 127.0.0.1 p 127.0.0.0/8 - This block is assigned for use as the Internet host loopback address.

The phrase originates from an IRC chat log in which a user named “bitchchecker” is tricked into attacking 127.0.0.1, an IP address that is typically designated for accessing the computer’s own network services, otherwise known as the localhost.
no typo: cannot ping 127.0.0.1 ? Herbert Rosmanith (firstname.lastname@example.org)Fri, 6 Sep 1996 07:36:25 +0200 (MET DST) Messages sorted by: Next message: Jared
The range 127.0.0.0 is reserved for host loopbacks (such as PCs), not routers or switches. The most commonly used address from this range is 127.0.0.1 – if you can’t ping that on a workstation, that means you can’t ping yourself, which means there’s a problem with the TCP/IP install itself.
