Ethernet ip header

WebIP header. An IP header is a prefix to an IP packet that contains information about the IP version, length of the packet, source and destination IP addresses, etc. It consists of the following fields: Version – the version of the IP protocol. For IPv4, this field has a value of 4. Header length – the length of the header in 32-bit words. WebPacketHeaders::from_ether_type for parsing a slice starting after an Ethernet II header; PacketHeaders::from_ip_slice for parsing from an IPv4 or IPv6 downwards; Manually slicing & parsing packets. It is also possible to manually slice & parse a packet. For each header type there is are metods that create a slice or struct from a memory slice.
