You cannot get that information based on what you have.

You would need to know the subnet mask to get 1, 2 and 4.

Yes, dfxdeimos is right!

But when you assume the default subnet mask of  255.255.0.0 for a class B network like 172.25.0.0, you could say that

- the address range of this network is 172.25.0.0 to 172.25.255.255
- the broadcast address is, according to the default subnet mask, 172.25.255.255

And, please, what is 'the block'?

Woolmilkporc is correct if you assume the default subnet mask (assuming it is a class B network).

I think he was referring to the range as the "block" as in "IP block"??

Forgive me please, in my many years in the business I got so acquainted to that old class A/B/C stuff ...

All of you are right - yes, we don't know anything without the subnet mask, and, yes, 172.25.n.n falls into one of the private IP address ranges.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

The Comment I gave was a serious effort at answering your question.  In fact, what part of your question was not answered by the Link that I gave?

There was nothing "immature" about the comments made by myself in reality, just in your opinion... It was simply a joke.

Also in response to "I hope you can reeducate some of our so called expert in what they posted" perhaps you are the one that needs a little re-education, since it is YOU who is posting the questions.

I disagree with your assessment and will leave it at that. Good day.
