<<<<<<<<<<<<<<<<<<<<<<<IPv4 to IPv6 Mapping >>>>>>>>>>>>>>>>>>>>>
map IPv4 adress in last 32 Bits of IPv6 Mapping address given above like:
Given:
1. IPv4 Mapping Address in hexadecimal
::FFFF:0:0/96	0000:0000:0000:0000:0000:FFFF:0000:0000

2. IPv4 address to be mapped
192.168.10.20	
map 192.168.10.20 to IPv6 address by converting IPv4 to Binary and then to hex Like

192.168.10.20								Decimal
11000000.10101000.00001010.00010100		Binary
C0.A8.0A.14								Hexadecimal

now place 32 bits IPv4 (hex format) in last 32 bits of given IPv6 address like

0000:0000:0000:0000:0000:FFFF:0000:0000		IPv6 in hex
0000:0000:0000:0000:0000:FFFF:C0A8:0A14		IPv4 mapped Ipv6

<<<<<<<<<<<<<<<<<<<<<<<IPv4 and IPv6 migration/transition techniques >>>>>>>>>>>>>>>>>>>>>
----------------Dual stack----------------
allows IPv4 and IPv6 to coexist on the same network segment. Dual stack devices run both IPv4 and IPv6 protocol stacks simultaneously. 
Known as native IPv6, this means the customer network has an IPv6 connection to their ISP and is able to access content found on the internet over IPv6.

------------------Tunneling------------------
is a method of transporting an IPv6 packet over an IPv4 network. The IPv6 packet is encapsulated inside an IPv4 packet, similar to other types of data.

---------------------------Network Address Translation 64 (NAT64)-------------------------
allows IPv6-enabled devices to communicate with IPv4-enabled devices using a translation technique similar to NAT for IPv4. 
An IPv6 packet is translated to an IPv4 packet and an IPv4 packet is translated to an IPv6 packet.



<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< IPv6 >>>>>>>>>>>>>>>>>>>>>>>>>>>>
128 bits
8 blocks/Hexets
each Hexet has 16 bits
written in HEXADECIMAL form
every octet sepaarted by colon ":"

----------------------IPv6 summarization/Shortening/Reducing Rules----------------------
1.
Remove Leading Zeros in any Hexet	e.g.
00AB:125F:0012:BCDE		IPv6 Example
AB:125F:12:BCDE			Reduced Form

2.
Leading zeros can be summarized/Reduced with double colon like

2001:0000:0000:1FA3:001F:012C:20AB:58BD	IPv6 Example
2001::1FA3:1F:12C:20AB:58BD				Reduced Form

2(a).
If zeros found in two consecutive hexets, two times in a Adresses, 
reduce only one consecutive zero Hexets with ::
and Reduce other pair of hexts by removing leading zeros

ABCD:0000:0000:1234:0000:0000:5678:BCDE	IPv6 Example
ABCD::1234:0:0:5678:BCDE					Reduced Form

2(b).
if once found 2 consecutive  zeros hexets and also anpther more than 2 consecutive zeros hexets i.e 3 or 4
Reduce more Consecutive zeros hexets
and reduce two consective zeros hexet by removing leading zeros

ABCD:0000:0000:1234:0000:0000:0000:BCDE	IPv6 Example
ABCD:0:0:1234::BCDE						Reduced Form

************************IPv6 Addresses Types****************************
-----------------IPv6 Reserved Addresses-----------------
2001:db8::/32			documentation purposes, including use in examples.
fc00::/7 to fdff::/7		Unique local addresses
FE80::/10				Link-local Address (LLA)	
::/0					Default Route
::1/128				Loopback
::/128				unspecified
FF00::/8				Multicast IPv6 Address
::FFFF:0:0/96			IPv4 Mapping Address

------------Unicast Addresses-----------
Range = 2000::/3	means first three bits of first hexet cannot be modified

for now only this range is assigned to Global registries by IANA
2000::/16	(2000) to (3FFF)		

------------Multicast Addresses-----------
prefix ff00::/8
ff00::1 = special case, means all nodes on a link

-------------Anycast Addresses-----------
it does not have any range
assign a same unicast adrress to all devices it will be considered as anycast adres in that network

*Note: IPv6 Does not use BROADCAST Address

******************************* Unicast Addresses Types*******************************
Global Unicast Address (GUA)	Like Public IPv4
Link-local Address (LLA)			Like APIPA in IPv4
Unique local addresses			Like Private IPv4
Loopback	::1/128				Like 127.0.0.0 /8 in IPv4
unspecified ::/128

-------------------1. Global Unicast Address (GUA)----------------------
This is similar to a public IPv4 address. These are globally unique, internet-routable addresses.
GUAs can be configured statically or assigned dynamically.

----------------GUAs IP Assignment Methods----------------
There are two ways in which a device can obtain an IPv6 GUA automatically:
1. Stateless Address Autoconfiguration (SLAAC)
2. Stateful: DHCPv6

----------------GUA Structure----------------
Global Routing Prefix	48 bits Networks
Subnet ID				16 bits sub/Super networks, can be used by routing prefix of interface ID.
Interface ID			64 bits Hosts
Total				128 Bits

Range = 2000::/3	means first three bits of first hexet cannot be modified
i.e
(2000) to (3FFF)	
0010 0000 0000 0000 (2000) to
0011 1111 1111 1111 (3FFF)

Currently, only /16 IPv6 GUAa are being assigned to RIRs by ICANN/IANA i.e
001 or 2001::/16

IPv6 GUA SUBNETS examples:
2001:db8:acad:1::/64	
2001:db8:acad:2::/64
2001:db8:acad:3::/64

IPv6 GUA HOSTS examples:
2001:db8:acad:1::1/64	2001:db8:acad:1::2/64	2001:db8:acad:1::3/64	Subnet 1
2001:db8:acad:2::1/64	2001:db8:acad:2::2/64	2001:db8:acad:2::3/64	Subnet 2
2001:db8:acad:3::1/64	2001:db8:acad:3::2/64	2001:db8:acad:3::3/64	Subnet 3

------------------------------------2. Unique local addresses-------------------------------------
*Unique local addresses are used for local addressing within a site or between a limited number of sites.
*Unique local addresses can be used for devices that will never need to access another network.
*Unique local addresses are not globally routed or translated to a global IPv6 address.
Range:
fc00::/7 to fdff::/7
Like Private IPv4

--------ULA Structure--------
FC00			16 Bits
Global ID			32 Bits
Subnet ID			16 Bits
Interface ID		64 Bits
Total			128 Bits
i.e
FC00:Global ID: 64-Bits interface ID

---------------------3. Link-local Address (LLA)-------------------
This is required for every IPv6-enabled device. LLAs are used to communicate with other devices on the same local link. 
With IPv6, the term link refers to a subnet. LLAs are confined to a single link. Their uniqueness must only be confirmed on 
that link because they are not routable beyond the link. In other words, routers will not forward packets with a link-local source or destination address.

----------------LLA IP Assignment Methods----------------
There are two ways that a device can obtain an LLA:

------1. Statically------
This means the device has been manually configured.
------2. Dynamically-----
This means the device creates its own interface ID by using randomly generated values 
or using the Extended Unique Identifier (EUI) method, 
which uses the client MAC address along with additional bits.

--------LLA Structure--------
FE80				16 Bits
0000:0000:0000	48 Bits
1/2 MAC Address	24 Bits		Part of interface ID
FFFE				16 BIts		Part of interface ID
1/2 MAC Address	24 Bits		Part of interface ID
Total			128 Bits
i.e
Network ID 64 Bits	FE80:0000:0000:0000: 
Interface ID 64 BIts	64-Bits interface ID[1/2 MAC Address + FFFE + 1/2 MAC Address]

---------interface ID process---------
Given:
MAC of machine		00:11:22:AA:BB:CC
FFFE

first make EUI value
break MAC from into two 24 bits Parts/separate VENDOR (OUI) and NIC ID in MAC
and Punch FFFE in b/w VENDOR and NIC ID
i.e 
00:11:22:  FFFE  :AA:BB:CC

convert fist hexadecimal octet in binary i.e 00
and compliment/invert or apply NOT operation on 7th bit from left
 i.e 0 to 1 & 1 to 0

00 hex		0000 0000 bin
02 hex		0000 0010 NOT-bin

now again merge into EUI, it is now Interface ID
i.e
02:11:22:  FFFE  :AA:BB:CC	Final Interface ID

-------Scope ID--------
The “%xx” value sometimes seen following an IPv6 address is called the scope ID. 
This is used to identify the interface to which a local address belongs.
fe80::5fff:575e:2914:3428%22
fe80::1:1%31

-----------------Range-----------------
The first hextet has a range
1111 1110 1000 0000 (fe80) to
1111 1110 1011 1111 (febf)

Complete Subnet address Range:
fe80::/10
fe80:0000:0000:0000:0000:0000:0000:0000/10
to
febf::/10
febf:0000:0000:0000:0000:0000:0000:0000/10

The /10 indicates that the first 10 bits:
1111 1110 10xx xxxx

----------------IPv6 LLA SUBNETS examples----------------
The double colon (::) following the "/" notation or prefix length defines that this is a Network Address
fe80::/10	to febf::/10

******************** Bogon IP Address Ranges ********************
information Source:
https://ipinfo.io/bogon

Some IP addresses and IP ranges are reserved for special use, such as for local or private networks, and should not appear on the public internet. These reserved ranges, along with other IP ranges that haven't yet been allocated and therefore also shouldn't appear on the public internet are sometimes known as bogons.

Because bogon IP addresses don't belong to a specific user or server on the internet, so there's no way to geolocate them. Therefore our IP geolocation API won't return location information for IP addresses within bogon ranges, but it will return a bogon field to indicate that the IP address is a bogon.
