ipv6

截止2019年11月26号，全球所有43亿个IPv4地址已全部分配完毕，这一情况也宣告着IPv6时代的正式来临。IPv6和5G一样是关系到国家安全和战略发展的重大事情。 IPv6简单来说，就是一个互联网协议，互联网数据是一组一组在传输的，从IPv4四到IPv6实际上就是数据传输分组方式的变化和传输总量的变化，从32位进化到了128位。带来的直接好处就是，域名地址的指数级别的增加和传输速度的加快。在IPv4时代，由于地址数量的紧张以及美国占据了将近50%的地址这一情况，导致我国分配到的地址少的可怜。在我国大部分的时候，都是用的临时动态IP或者是私人架设IP，这对于网络溯源造成了相当大的麻烦，也就是没有办法针对犯罪行为进行溯源定位，增加了对网络犯罪管控的难度。而IPv6因为拥有大量地址，对网络实名制的构想有望达成，同时由于其增加了对信息的强制加密和收发端的识别功能，对于整体的网络信息安全的保护都有着很大的帮助。 互联网的安全关系到互联网金融的安全性，对于信息安全的加强将会促进互联网金融的发展更加的迅速。同时，IPv6技术对于我国发展人工智能、物联网等方面也会起到积极的推动作用。 以下内容摘自百科： https://baike.so.com/doc/1922913-2034393.html IPv4，是 互联网协议 (Internet Protocol，IP)的第四版

Hello everyone i am new here so please be kind. I have been using scapy lately in order to send and recieve ipv6 packets to selected ipv6 enabled servers. The gist of the code is here: text = line[:-1] #destination=getIPv6Addr(line[:-1]) destination="2607:f1c0:1000:60e0:7992:97f7:61b2:2814" source="2001:630:d0:f105:5cfe:e988:421a:a7b7" syn = IPv6(dst=destination,src=source) / TCP(sport=555,dport=80,flags="S")#flag S is syn packet syn.show() syn_ack = sr1(syn,timeout=11) When i execute the code hoever this is what i get: Begin emission: Finished to send 1 packets. .................WARNING: No

Just as we have rules governing the validity of an IPv4 netmask, does IPv6 have its own set of rules to qualify a netmask? Thanks! What is your use case? Normally in IPv6 your addresses will be auto-generated from a /64 prefix your router provides. You don't usually see a netmask written out in IPv6. Usually you will see a prefix length. For example: 2001:db8:0:160::/64 would have a netmask of ffff:ffff:ffff:ffff:: But you would only ever see the former. Technically the better answer may be that with IPv6 you no longer have a netmask. With IPv6 you have a "prefix length" which you can

Actually I'm porting an IPv4 server application to a dualstack IPv4/IPv6 application on Linux. The basic function I have solved by using: serv_addr.sin6_family = AF_INET6; serv_addr.sin6_addr = in6addr_any; ... bind(sock, (struct sockaddr *) &serv_addr, sizeof(serv_addr)); ... listen(sock, 5); ... newsock = accept(syn->sock, (struct sockaddr *) &cli_addr, &clilen); I can connect with IPv4 and IPv6 and use the connections. But when I want to get the IP with: switch(data->sa_family) { case AF_INET: inet_ntop(AF_INET, &(((struct sockaddr_in*)data)->sin_addr), buffer, size); break; case AF_INET6:

In IPV6 how to build CURL POST http request with the IPV6 address and port number.Any kind of thread will be appreciated. Tried to build the request as below >curl --interface 'http://[2001:0:db8:1111:0:0:0:11]:8091/?' But above gave error as "curl: NO URL specified" >curl -X POST -d curl -X POST `http://[2001:0:db8:1111:0:0:0:11]:8091/?` Then tried the above that gave error as >bash: http://[2001:0:db8:1111:0:0:0:11]:8091/?: No such file or directory curl: no URL specified! curl: try 'curl --help' or 'curl --manual' for more information Is there any alternate method, other than using URL curl

I am trying to port ipv4 applications to ipv6 but I can't bind the socket to the ipv6 address. The problem is here: err=bind(listening, (sockaddr*)&hint, sizeof(hint)); The err should be 0 but in this code it returns -1. What is going wrong ? SOCKET listening = socket(AF_INET6, SOCK_STREAM, 0); if (listening == INVALID_SOCKET) { cerr << "Can't create a socket! Quitting" << endl; return; } int err; // Bind the ip address and port to a socket sockaddr_in6 hint; hint.sin6_family = AF_INET6; hint.sin6_flowinfo = 0; hint.sin6_port = htons(54000); hint.sin6_addr = in6addr_any; err=bind(listening,

北京时间 2019 年 11 月 26 日下午，负责互联网资源分配的最后一个信息中心——欧洲网络信息中心（RIPE NCC）宣布耗尽了最后一个 IPv4 地址区块，至此，全球所有 43 亿个 IPv4 地址已全部分配完毕。 IPv4迄今为止已经使用了30多年。最早期的时候，互联网只是设计给美国军方用的，根本没有考虑到它会变得如此庞大，成为全球网络。 进入21世纪后，随着计算机和智能手机的迅速普及，互联网开始爆发性发展，越来越多的上网设备出现，越来越多的人开始连接互联网。这就意味着，需要越来越多的IP地址。 地址不够的问题，其实早在1990年，IETF（互联网工程任务小组，成立于1985年底，是全球互联网最具权威的技术标准化组织）就开始规划IPv4的下一代协议。 没错，就是号称可以“给地球上每一颗沙子都分配一个IP的 IPv6 ”。 另外，按照本世纪初专家们的预测，我们IPv4的地址早已枯竭几万次了。之所以能够“苟活”到现在，主要是除了IPv6之外，我们还有一些技术，可以变相地缓解地址不足，例如NAT（Network Address Translation，网络地址转换）。 而上个月，在乌镇举办的第六届世界互联网大会上，中国电信就表示：“中国电信城域网、移动网、骨干网、IDC等均实现了IPv6的商用部署，目前已建成规模最大、业务形态最全的IPv6网络”，
