There really is no default subnet mask - any network equipment that you set up will require a netmask be provided. The netmask you provided only refers to a specific host; the network on which the host resides can be split up in numerous ways, depending on how the network admins set it up.

∙ 14y agoThe answer depends on the subnet mask being used. 172.12.4.22 is a "class B" address so the default subnet mask is 255.255.0.0 or /16 (each 255 represents 8 binary ones. 8+8 = /16). The default subnet mask would put this IP in the Class B network 172.12.0.0 with a range of valid IP addresses from 172.12.0.1 to 172.12.255.254. 172.12.0.0 is the network address and 172.12.255.255 is the broadcast address each of which are generally not usable (There are special circumstances where they could be used) Typically, entire Class B networks are not issued to one party unless it's an ISP. More likely someone requiring a block of IP's would be issued a subnet of a class network like perhaps 172.12.4.0 /22. This would allow them use of IP's from 172.12.4.0 to 172.12.7.255 (1024 ip addresses). 172.12.4.22 would fall into this subnet. But the company acquiring the block of IP's might want to break it up into a bunch of much smaller subnets so 172.12.4.22 could belong to any of the following subnets of Class B network 172.12.0.0/16 ... 172.12.0.0/17 - 172.12.0.0/18 - 172.12.0.0/19 - 172.12.0.0/20 - 172.12.0.0/21 172.12.4.0/22 - 172.12.4.0/23 - 172.12.4.0/24 - 172.12.4.0/25 - 172.12.4.0/26 172.12.4.0/27 - 172.12.4.16/28 - 172.12.4.16/29 - 172.12.4.20/30

∙ 14y agoYou have not provided enough information for the question to be answered completely and correctly. The subnet mask for that IP address could be anything in a class B range of 255.255.0.0/16. The private IP addressing for that specific IP address that you gave is in a class B range. If I had to guess however, I would start with 255.255.0.0 and then go from there:
They all start with 255.255.
255.0
192.0.
224.0
240.0
248.0
252.0
255.128
255.192
255.240
255.248
255.252

Defference bw a default subnet mask and a custom subnet mask?
The default subnet mask has a standard size. The custom subnet mask allows you to make subnets that are smaller or larger than the default.
What is the default subnet mask for the 198.25.4.129 address?
255.255.255.0
What class has subnet mask 225.225.225.0?
If this is a default subnet mask, then it would be a class C subnet mask. If you are subnetting a network and this is not the default subnet mask, then it could be either a class A or class B.
What is the default subnet mask for a Class A network?
255.0.0.0The default subnet mask of a class A network is 255.0.0.0
What is the subnet mask of IP address 188.88.0.0?
255.255.255.0
What is the motivation behind using a custom subnet mask versus the default subnet mask?
A default subnet mask gives you classful addressing on octet boundaries. A non-default subnet mask implies that you are subnetting a larger network into several smaller ones.
What is the subnet mask for 176.42.53.18?
The default subnet mask would be 255.255.0.0 for a class B address.
What is the default subnet mask for the IP address 72.224.56.62?
Since this is a Class C address, the default network mask is 255.255.255.0.Since this is a Class C address, the default network mask is 255.255.255.0.Since this is a Class C address, the default network mask is 255.255.255.0.Since this is a Class C address, the default network mask is 255.255.255.0.
The default subnet mask for the host IPv4 address 123.232.203.145 is?
The default subnet mask for this address - a class A address - is 255.0.0.0 (same as /8).
Which two automatic addressing assignments are supported by DHCP?
subnet mask default gateway address
What subnet mask is used for 192.168.12.526?
It depends on whether you are subnetting or not. If not, the default subnet mask would be 255.255.255.0
What is the default subnet mask of 22.1.2.3?
255.0.0.0
