Public IP Range

[Denisjf]

Hi,

Is there a way to determine what the range of public ip addresses sky uses to assign to me?

I presume sky owns a block of ip addresses which are assigined dynamically 

Thanks

There are commercial services which will read into the RIPE database, but these are likely to return too many results to be particularly useful.

For example:

https://ip-netblocks.whoisxmlapi.com 

Putting 'Sky UK' in there hits a limit of 100 results, each for a different block.

@TimmyBGood thanks for your reply.

I tried entering my ip here and it gave me the following range

213.0.0.0 - 213.255.255.255

@Denisjf given Sky have in excess of 6 million customers each of which if connected will have a unique IP4 public IP address you can expect a significant number of different blocks and sub-blocks.

That's a Class A range containing some 16.7 million addresses: Sky doesn't own a Class A (I don't think any single ISP does) and it would be hugely wasteful if they did.
