The System.Uri class is not behaving as I expect when an IPv4 address is
embedded within an IPv6 address. The following test works fine, using IPv6
only:
[Test]
public void Uri_ShouldCreat eValidUriFromSi mpleIPv6Address ()
{
Uri testUri = new Uri("http://[::1]:9050");
Assert.AreEqual (
"http://[0000:0000:0000: 0000:0000:0000: 0000:0001]:9050/",
testUri.ToStrin g());
}
However, when I embed an IPv4 address, the Uri class begins converting the
address in a way that I do not expect:
public void Uri_ShouldCreat eValidUriFromIP v4AddressEmbedd edWithinIPv6Add ress()
[Test]
{
Uri testUri = new Uri("http://[::101.45.75.219]:9050");
Assert.AreEqual (
"http://[0000:0000:0000: 0000:0000:0000: 101.45.75.219]:9050/",
testUri.ToStrin g());
}
TestCase 'Uri_ShouldCrea teValidUriFromI Pv4AddressEmbed dedWithinIPv6Ad dress'
failed:
String lengths differ. Expected length=58, but was length=54.

I'm not sure if this is a question about python socket support or sockets in
general ...
I have a socket server with which I want to accept incoming connections on
ipv4 and ipv6.
I've found that if I create the listening socket with
sock = socket(AF_INET, SOCK_STREAM)
it will accept connections on ipv4 (only) and if I create it with
sock = socket(AF_INET6, SOCK_STREAM)
it will accept connections with ipv6 (only)

I have a problem. I want to use httplib to a site that has both IPv4 and

Is there a way to force httplib to use IPv6 only, or to at least try
IPv6 before IPv4? As it is now, httplib always takes the IPv4 address
first.
If there isn't a way to do this, i.e. httplib always connects to the IPv4
address first, and there is now way to change that, who do I talk to

Anyone,
I am writting a server that accepts a list of IPv4 and IPv6 address.
The IPv4 address are padded with leading zeros. I belive this allows me to
just point to the beging and run both IPv4 addresses and IPv6 address though
the same conversion function. However, i am having a hard time finding a
simple way to this. I do not want to communicate with the addresses so i
would like to avoid setting up anything extra.
So does anyone...

Hello All,
I have some queries related to python support for IPv6. Can you kindly
clarify the doubts which I have -
1. Does python support IPv6?
2. Does it support setting of QoS flags?
3. Does it support tunneling of IPv6 on a IPv4 network?
4. If an IPv4 address is given, does it support this on a IPv6 network?
If not can you kindly let me know, Are there any plans for supporting these
features in future?

Hi,
is there a straight forward way of converting IPv4 to IPv6?
I thought that it was just a matter of converting 32 bits to 128 bits, (by
adding 96 leading 0s), but that does not seem right in some/most cases.
For example, 127.0.0.1, (IPv4 localhost), does not convert ::1, (IPv6
localhost)

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
