How would I convert an IPv6 address into a big.Int?

<p>I need to convert an IPv6 address into a big.Int (I need to compare an IPv6 address to other&#39;s, for IPGeolocation). How should I approach this? </p> <hr/>**评论：**<br/><br/>hobbified: <pre><p>Nothing to it: <code>x := new(big.Int).SetBytes( net.ParseIP(...).To16() )</code></p></pre>bupku5: <pre><p>leave it in the native representation (<code>[]byte</code>)...once you understand how ipv6 works it should be straightforward to determine how to mask/shift the parts you need to compare to find CIDRs etc</p> <p>converting to ints tells me you are trying to do something like php&#39;s integer representation for ipv4 addresses, which is clumsy and not necessary...Go&#39;s big Int type is not that useful and has limited functionality...it is also not well suited for efficient storage in dbs</p> <p>stick with the native representation</p></pre>victor_lowther: <pre><p>And when you need to do math on your ipv6 addresses, are you going to reimplement what big.Int already gives you?</p></pre>
