The builtin .Net method System.Net.IPAddress.ToString() behaves inconsistently for IPv6 addresses. Given the byte array 0xAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA , in some environments "aaaa:aaaa:aaaa:aaaa:aaaa:aaaa:aaaa:aaaa" is returned, whereas others return "aaaa:aaaa:aaaa:aaaa:aaaa:aaaa:172.172.172.172" . I understand that both are valid IPv6 formats, but I would like to be able to explain the difference. It seems that newer environments (Windows 7 and Server 2008 R2) are more likely to produce the first behaviour, so I've checked obvious differences like .Net framework version, but I've been

I am curious about the usefulness of NAT and NAT traversal mechanisms once the deployment and usage of IPv6 increases. We have so many NAT traversal mechanisms (including proprietary) which are intended for mainly IPv4 devices/clients which are behind some kind of residential or enterprise NAT's. Given that NAT came about because of the lack of available addresses in IPv4, is it likely to become redundant once IPv6 is adopted widely in the coming years since IPv6 has enough addresses? Of course, I do understand that adoption of IPv6 will not happen overnight and it is a gradual and painful

I am using docker 1.12.1 on Ubuntu 16.04, and docker-compose 1.8.1. I am trying to get the Compose file from https://docs.docker.com/compose/compose-file/#ipv4-address-ipv6-address to run. For reference, I created docker-compose.yml with the following content: version: '2' services: app: image: busybox command: ifconfig networks: app_net: ipv4_address: 172.16.238.10 ipv6_address: 2001:3984:3989::10 networks: app_net: driver: bridge driver_opts: com.docker.network.enable_ipv6: "true" ipam: driver: default config: - subnet: 172.16.238.0/24 gateway: 172.16.238.1 - subnet: 2001:3984:3989::/64

I have a program that uses gethostbyname (in Windows) in order to convert IP address to hostname. But, it works only for IPv4... What is the correct replacement for IPv6? Thanks. Looking up gethostbyname in MSDN tells us that it's deprecated and we should look at getaddrinfo , which has all kinds of options for dealing with other addressing families. Or if you're doing address to name translation, you'll end up at getnameinfo Use getaddrinfo , which deprecates the old gethostbyname function. 来源： https://stackoverflow.com/questions/2598965/gethostbyname-replacement-for-ipv6-addresses

Anyone have a good (preferably tested) regex for accpeting only a valid DNS hostname, IPv4 or IPv6 address? I understand that you may be forced to use a regex. However, if possible it is better to avoid using regexes for this task and use a Java library class to do the validation instead. If you want to do validation and DNS lookup together, then InetAddress.getByName(String) is a good choice. This will cope with DNS, IPv4 and IPv6 in one go, and it returns you a neatly wrapped InetAddress instance that contains both the DNS name (if provided) and the IPv4 or IPv6 address. If you just want to

Would it be possible to run Flask to listen in both IPv4 and IPv6 (i.e. dual IP stack)? As far as I checked it is possible to run either in IPv4 using: app.run(host='0.0.0.0', port=port, debug=True) or IPv6 using app.run(host='::', port=port, debug=True) but I haven't find a way of running in both at the same time (it is possible to have an instance of my Flask application listening to IPv4 and another instance listening to IPv6, but both cannot listen to the same port). Thanks! Update (additional info): Followingt Sander Steffann comments (thanks!), I have started my app listening in IPv6: *

I have some code in an asp.net app that needsto get the ipv4 address of the client computer (the users are all on our own network). Recently we upgraded the server the app runs on to windows 2008 server. Now the Request.UserHostAddress code returns the ipv4 when the client is on an older OS and ipv6 when they are on a newer OS (Vista and higher). So the feature that relys on this works for some clients and not others. I added code that is supposed to convert from ipv6 to ipv4 to try to fix this problem. It's from this online tutorial: http://www.4guysfromrolla.com/articles/071807-1.aspx .I'm

I use Request.UserHostAddress , can only get IPv4 address, how to get IPv6 address of a visitor? I assume you're talking about HttpRequest.UserHostAddress . It will always return the address that was used to connect to you. If the request was made over IPv6, it will return their IPv6 address; if the request was made over IPv4, it will return their IPv4 address. You should start by investigating why the request is being made over IPv4. And the folks at http://serverfault.com will probably be of more help on that. An IPv4 address is translated to an IPv6 address by placing the 4 octets of the
