-// Ethernet is a large, diverse family of frame-based computer networking technologies
-// that operates at many speeds for local area networks (LANs).
-// The name comes from the physical concept of the ether.
-// It defines a number of wiring and signaling standards for the physical layer,
-// through means of network access at the Media Access Control (MAC)/Data Link Layer,
-// and a common addressing format.
-//
-// Ethernet has been standardized as IEEE 802.3.
-// The combination of the twisted pair versions of ethernet for connecting end systems to
-// the network with the fiber optic versions for site backbones
-// become the most widespread wired LAN technology in use from the 1990s to the present,
-// largely replacing competing LAN standards such as coaxial cable Ethernet,
-// token ring, FDDI, and ARCNET. In recent years, Wi-Fi,
-// the wireless LAN standardized by IEEE 802.11,
-// has been used instead of Ethernet for many home and small office networks
-// and in addition to Ethernet in larger installations.

-//
-// Address Resolution Protocol (ARP) is the method for finding a host's hardware address
-// when only its network layer address is known.
-// Due to the overwhelming prevalence of IPv4 and Ethernet,
-// ARP is primarily used to translate IP addresses to Ethernet MAC addresses.
-// It is also used for IP over other LAN technologies,
-// such as Token Ring, FDDI, or IEEE 802.11, and for IP over ATM.
-//
-// ARP is used in four cases of two hosts communicating:
-//
-// 1. When two hosts are on the same network and one desires to send a packet to the other
-// 2. When two hosts are on different networks and must use a gateway/router to reach the other host
-// 3. When a router needs to forward a packet for one host through another router
-// 4. When a router needs to forward a packet from one host to the destination host on the same network

-IP4 header:
-
- 1. Version. 4 bits.
- Specifies the format of the IP packet header.
- 4 --- IP, Internet Protocol.
- 2. IHL, Internet Header Length. 4 bits.
- Specifies the length of the IP packet header in 32 bit words.
- The minimum value for a valid header is 5.
-
- 3. Differentiated Services. 8 bits.
-
- 4. Codepoint. 6 bits.
-
- 5. unused. 2 bits.
-
- 6. TOS, Type of Service. 8 bits.
-
- 7. Total length. 16 bits.
- Contains the length of the datagram.
-
- 8. Identification. 16 bits.
- Used to identify the fragments of one datagram from those of another.
- The originating protocol module of an internet datagram sets the identification field to a value that must be unique for that source-destination pair and protocol for the time the datagram will be active in the internet system. The originating protocol module of a complete datagram clears the MF bit to zero and the Fragment Offset field to zero.
-
- 9. Flags. 3 bits.
- 9.A R, reserved. 1 bit.
- Should be cleared to 0.
- 9.B DF, Don't fragment. 1 bit.
- Controls the fragmentation of the datagram.
- 9.C MF, More fragments. 1 bit.
- Indicates if the datagram contains additional fragments.
-
- 10. Fragment Offset. 13 bits.
-
- 11. TTL, Time to Live. 8 bits.
- A timer field used to track the lifetime of the datagram.
- When the TTL field is decremented down to zero, the datagram is discarded.
-
- 12. Protocol. 8 bits.
- This field specifies the next encapsulated protocol.
-
- 1 -- ICMP, Internet Control Message Protocol.
- 2 -- IGAP, IGMP for user Authentication Protocol.
- IGMP, Internet Group Management Protocol.
- RGMP, Router-port Group Management Protocol.

-/*******************************************************
- Arp Packet Format
- [15:0] - HRD = 1
- [15:0] - PRO = 0x0800
- [7:0] - HLN = 6
- [7:0] - PLN = 4
- [15:0] - OP
- [47:0] - SHA [0-5]
- [31:0] - SPA [0-3]
- [47:0] - THA [0-5]
- [31:0] - TPA [0-3]
-
-HRD (Hardware Type): This field specfies the type of hardware used for the local network
-transmitting the ARP message.
- 1 - Ethernet (10MB)
- 6 - IEEE 802 Networks
- 7 - ARCNET
- 15 - Frame Relay
- 16 - Asynhronous Transfer Mode (ATM)
- 17 - HDLC
- 18 - Fibre Channel
- 19 - Asynchronous
-
-
-PRO (Protocol Type): This field is the complement of the Hardware Type field,
- specifying the type of layer three addresses used in the message.
- For IPv4 addresses, this value is 2048 (0800 hex),
- which corresponds to the EtherType code for the Internet Protocol.
-
-HLN (Hardware Address Length):
- Specifies how long hardware addresses are in this message.
- For Ethernet or other networks using IEEE 802 MAC addresses, the value is 6.
-
-PLN (Protocol Address Length):
- The complement of the preceding field; specifies how long protocol (layer three)
- addresses are in this message. For IP(v4) addresses this value is of course 4.
-
-OP (Opcode): This field specifes the nature of the Arp Message being sent
- 1 -- ARP Request
- 2 -- ARP Reply
- 3 -- RARP Request
- 4 -- RARP Reply
- 5 -- DRARP Request
- 6 -- DRARP Reply
- 7 -- DRARP Error
- 8 -- InARP Request
- 9 -- InARP Reply
-
-SHA (Sender Hardware Address):
- The hardware (layer two) address of the device sending this message
-
-SPA (Sender Protocol Address):
- The IP address of the device sending this message.
-
-THA (Target Hardware Address):
- The hardware (layer two) address of the device this message is being sent to.
-
-TPA (Target Protocol Address):
- The IP address of the device this message is being sent to.

+// ip.c: IP protocol processing
+/************************************************************
+IP4 header:
+
+ 1. Version. 4 bits.
+ Specifies the format of the IP packet header.
+ 4 --- IP, Internet Protocol.
+ 2. IHL, Internet Header Length. 4 bits.
+ Specifies the length of the IP packet header in 32 bit words.
+ The minimum value for a valid header is 5.
+
+ 3. Differentiated Services. 8 bits.
+
+ 4. Codepoint. 6 bits.
+
+ 5. unused. 2 bits.
+
+ 6. TOS, Type of Service. 8 bits.
+
+ 7. Total length. 16 bits.
+ Contains the length of the datagram.
+
+ 8. Identification. 16 bits.
+ Used to identify the fragments of one datagram from those of another.
+ The originating protocol module of an internet datagram sets the identification field to a value that must be unique for that source-destination pair and protocol for the time the datagram will be active in the internet system. The originating protocol module of a complete datagram clears the MF bit to zero and the Fragment Offset field to zero.
+
+ 9. Flags. 3 bits.
+ 9.A R, reserved. 1 bit.
+ Should be cleared to 0.
+ 9.B DF, Don't fragment. 1 bit.
+ Controls the fragmentation of the datagram.
+ 9.C MF, More fragments. 1 bit.
+ Indicates if the datagram contains additional fragments.
+
+ 10. Fragment Offset. 13 bits.
+
+ 11. TTL, Time to Live. 8 bits.
+ A timer field used to track the lifetime of the datagram.
+ When the TTL field is decremented down to zero, the datagram is discarded.
+
+ 12. Protocol. 8 bits.
+ This field specifies the next encapsulated protocol.
+
+ 1 -- ICMP, Internet Control Message Protocol.
+ 2 -- IGAP, IGMP for user Authentication Protocol.
+ IGMP, Internet Group Management Protocol.
+ RGMP, Router-port Group Management Protocol.
+ 4 -- IP in IP encapsulation.
+ 6 -- TCP, Transmission Control Protocol.
+ 17-- UDP, User Datagram Protocol.
+ 41-- IPv6 over IPv4.
+ 58-- ICMPv6, Internet Control Message Protocol for IPv6.
+ MLD, Multicast Listener Discovery.
+ 59-- IPv6 No Next Header.
+ 97-- EtherIP.

+== MicroWeb v0.01 ==
+
+This program is a Web Server and TCP/IP stack for 8051 microcontrollers.
+It started out as my Senior Project while a Senior at Bradley University.
+I hope to expand it to work on other microcontrollers and be used in a
+variety of applications.
+
+This version is meant to be compiled with SDCC on Linux.

+// Ethernet is a large, diverse family of frame-based computer networking technologies
+// that operates at many speeds for local area networks (LANs).
+// The name comes from the physical concept of the ether.
+// It defines a number of wiring and signaling standards for the physical layer,
+// through means of network access at the Media Access Control (MAC)/Data Link Layer,
+// and a common addressing format.
+//
+// Ethernet has been standardized as IEEE 802.3.
+// The combination of the twisted pair versions of ethernet for connecting end systems to
+// the network with the fiber optic versions for site backbones
+// become the most widespread wired LAN technology in use from the 1990s to the present,
+// largely replacing competing LAN standards such as coaxial cable Ethernet,
+// token ring, FDDI, and ARCNET. In recent years, Wi-Fi,
+// the wireless LAN standardized by IEEE 802.11,
+// has been used instead of Ethernet for many home and small office networks
+// and in addition to Ethernet in larger installations.
