I known that I can refer to all IPv4 IP addresses with mask 0.0.0.0/0.
What is the address that matches all IPv6 IP addresses?
It is ::/0, which is short for 0000:0000:0000:0000:0000:0000:0000:0000/0.

I'm relatively new to the IP Address concept and trying to build a range checker.
USE CASE: The user gives one IP Address(can be IPv4/IPv6) and a range(can be 2 IPv4 addresses /2 IPv6 addresses/ 1 IPv4 and 1 IPv6 address).
I need to test if the given IP exists between the specified range.
I just wanted to know if the below cases are possible
Can an IPv4 address exist between 2 IPv6 addresses?
Can an IPv6 address exist between 2 IPv4 addresses?
Can an IP range be 1 IPV4 address and 1 IPv6 address or do IP ranges implicitly mean the same types(like fromIPv4 - toIPv4, fromIPv6 - toIPv6)?
Note: When talking about IPv6 addresses, I mean all IPv6 addresses and not just those that can be mapped to IPv4.
IPV6 and IPV4 is two different protocols, that don't intersect at all
Just check what pattern IPV4 matches and what pattern IPV6 matches
IPV4 consist of four parts, each part has value from 0-255 and separated with dot.
IPV6 consist of 8 octets, separated with colon sign.
And main reason, why it's unreal to find out, is that IPV4 use netmask for dividing IP address on network part and host part
At the same time IPV6 address is strictly divided on Routing prefix and interface id
For example, the CIDR notation for the IPv4 block 192.168.100.0/22 represents the 1024 IPv4 addresses from 192.168.100.0 to 192.168.103.255.
I'm in an environment where everything is blocked by default, so need to open up the full IPv4-address space on port 443 to give the world access through https.
What is the CIDR notation for all IPv4 addresses?
The so called default route is 0.0.0.0/0 and matches any IPv4 address.
Ex: My Target IP address is 10.7.19.119
And My IP address is 10.7.1.166
and Subnet mask is 255.255.192.0
You can not simply calculate a subnet mask from just an IP address.
But you can try to get that info from your router/dhcp server.
I would try to assign your pc an IP address next to 10.7.19.119 for example: 10.7.19.120.
Afterwards check your subnet mask with ipconfig excecuted in a command shell (cmd).
Very Much confused about assigning IP address to WAN Interface and LAN Interface on Router/Firewall.
I know the process of assigning IP address but don't know which IP address to assign. Support My default gateway for ISP is 14.141.46.129, then what IP should I assign to my WAN Interface? And what Subnet Mask I have to assign?
Now What IP address I should assign to LAN Interface? And what Subnet Mask I have to assign?
After Assigning IP, I have to get Internet access from My LAN interface to WAN Interface.....
How to find the route to WAN Interface so that I Can ping google.com??
First, 14.141.46.129 is a valid IP address. The WAN interface needs a public IP address which should be given by your ISP provider.you can covert through cyberoam interface A port for-wan, B port for local lan & new range of 192.168.2.1 to 192.168.2.255 subnet mask 255.255.255.0 as u need you have to covert in subnetmask 192.168.2.1/32 to as per your needing (You assing your local ip for Lan The LAN interface can be in the range 192.168.2.2-254 with a mask of 255.255.255.0, )
First, 14.141.46.129 is not a valid IP address.
The WAN interface needs a public IP address which should be given by your ISP provider.
The LAN interface can be in the range 192.168.1.2-254 with a mask of 255.255.255.0
I was studying about IP addresses when I came Across an address of type 127.0.0.1/8. I know that127.0.0.1 is a loop-back address but what did /8 mean in the address.what /8 (in 127.0.0.1/8) specify
the /8 in your ip is the subnet mask.
It allows you to know on which subnetwork you are, find your broadcast and unicast IP.
Take a look at http://en.wikipedia.org/wiki/Subnetwork to have more informations
/8 is a subnet mask written in CIDR notation and which is used by hosts to determine if they are on the same network as some other host and can communicate directly or they need to use a router (default gateway). In your case this is a loopback address, and actually all IP addresses from 127.0.0.0/8 network (from 127.0.0.0 to 127.255.255.255) are reserved loopback addresses as defined in rfc6890: Special-Purpose Address Registries
