It can also be used to restrict access to or from a particular geographic area; for example, syndicating content to a specific region through the use of Internet geolocation. [ 1 ] IP address blocking can be implemented with a hosts file (e.g., for Mac, Windows, Android, or OS X) or with a TCP wrapper (for Unix-like operating systems).
For example, to find the domain name associated with the IP address 203.0.113.22, one would send a PTR query for 22.133.0.203.in-addr.arpa. Misconfigured hosts [5] often send reverse DNS queries for private addresses to the public DNS. The public DNS cannot meaningfully respond to these queries, since these addresses are reserved for private ...
The ICMP header starts after the IPv4 header and is identified by its protocol number, 1. [6] All ICMP packets have an eight-byte header and variable-sized data section. The first four bytes of the header have fixed format, while the last four bytes depend on the type and code of the ICMP packet.

PRIVATE WIFI also works for wired internet connections About PRIVATE WiFi™ PRIVATE WiFi is a virtual private network (VPN) security software that protects your identity and sensitive information by encrypting everything you send and receive over public WiFi networks so that your online activity is invisible to threats.
In Internet networking, a private network is a computer network that uses a private address space of IP addresses. These addresses are commonly used for local area networks (LANs) in residential, office, and enterprise environments. Both the IPv4 and the IPv6 specifications define private IP address ranges.

Network address translation between a private network and the Internet. Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. [1]
