NAME # ip - Internet Protocol
SYNOPSIS # #include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
int
socket(AF_INET, SOCK_RAW, proto);
DESCRIPTION # IP is the network layer protocol used by the Internet protocol family. Options may be set at the IP level when using higher-level protocols that are based on IP (such as TCP and UDP). It may also be accessed through a “raw socket” when developing new protocols, or special-purpose applications.

IPCOMP(4) - Device Drivers Manual # IPCOMP(4) - Device Drivers Manual
NAME # ipcomp - IP Payload Compression Protocol
DESCRIPTION # IPComp is enabled with the following sysctl(2) variable in /etc/sysctl.conf:
net.inet.ipcomp.enable
IPComp is a protocol used to reduce the size of IP datagrams. It can be used to enhance the communication performance between a pair of hosts/gateways, especially on slow links, by compressing the datagrams, provided the communicating entities have enough computational power.
