Are all 172 IP addresses private?

Is 172.32 0.1 A private IP address?

I don't know if this is the correct place to ask this question, so I apologize if it is not. In order to provide a network interface for computers in a home with my parents' ISP, I purchased a Linksys wireless router and router modem. While I am at home, I log into the router's web page, and enter the IP address given to me when I purchased the router. It was 192.168. I then configured the router to share internet through my computer, by setting the WAN settings to the same number and subnet as my computer, namely 172.32.102. When I go to the router's web page, the address displayed is 172.1, but when I enter this into a browser, the address turns out to be 172. Am I doing this correctly?
If not, what should I do? That IP address is not your private IP address. It is the public IP address of your computer on the Internet.

If you are using private networking, then you probably got that IP from your router. To check that, go to the "router's settings" page, and look for the Network Address Settings. That will tell you what private IP addresses you can use.

Are all 172 IP addresses private?

So a few days ago I was having trouble with my DNS settings and was getting a dns request to an IP address that was not in my DNS, specifically 172.16.64:80. This seems to be reserved for a specific purpose which I cannot tell, but the server that I was on didn't have an issue with it. After a little research I found that 172.64 is a private address that is reserved for use by certain organizations. So now I'm wondering how many of these private addresses are actually publicly available and if they all are.

Yes, every IP address in the range 172.0/16 is reserved for private use.

And no, not all of those are publicly available. The RFCs covering this address range are RFC 1912, RFC 1918, and RFC 6890.

RFC 1912 describes the 172.0/12 address block as "Private Use" and describes the 172.0/16 address block as "Internet Draft".

RFC 1918 describes the 172.0/14 address block as "Private Use" and describes the 172.

RFC 6890 describes the 172. The document you linked to is just an Internet Draft. An Internet Draft is a working draft of a protocol. It's not a formal specification. While it may be published as a "RFC", it isn't a requirement for it to be published as an "RFC".

The RFC series is a series of "requirements" documents. The first RFC, RFC 791, describes the Address Allocation and Routing Requirements for Internet Hosts.

RFC 791 was initially published in 1981. It was updated in 1995. There's an RFC 2271 which is its current revision.

What is Private IP and its range?

I mean what would be the valid private IPs of the same machine. And if there is any valid IP which isn't in the range of 128.0-191.255.

Re: What is Private IP and its range? The whole IPv4 address space is divided into different classes of networks, and networks within a class are assigned to different Autonomous System identifiers (ASNs). Some portions of an Autonomous System's address space may be designated as "private" for the purposes of providing network services only to organizations with an Autonomous System identifier allocated for that purpose. The following discussion focuses on the scope of the term "Private IP".

The "Class A" addresses are defined as being within the ranges of: IP addresses with a value between 0 and 255 (ie, in octets). For example: 45.10 is a Class A IP address 21.17 is a Class A IP address 22.0/16 is a Class A network 168.0/16 is a Class C network 1 is a loopback address. Private IP addresses are those with a value within the ranges: 0 - 191.255 The "Class B" addresses are defined as being within the ranges: IP addresses with a value between 256 and 383 (ie, in octets). 0 is a Class B network. 254.0 is a Class B network The "Class C" addresses are defined as being within the ranges: IP addresses with a value greater than 384 (ie, in octets). 0 - 127.255 255

The "Unassigned" addresses are reserved for future use by private network administrators.
