原题：The State of IPv6 support on the Tor network
In our last article, published in RIPE's website, we described the work that happened in 2020 related to giving IPv6 support to the Tor network.
Tor 0.4.5.1-alpha is the first release that includes all the work described in the RIPE article. Relays running 0.4.5.1-alpha are the first to report IPv6 bandwidth statistics.
As of December 2, 2020, 54% of the relays on the network run a version of Tor that supports IPv6. Of the 6852 relays in the network, 3587 are running version 0.4.4 and 8 relays are running the latest Tor version 0.4.5. From all those, 1588 are announcing an IPv6 address and port for the OR protocol. 1587 relays are reachable on IPv6 by the directory authorities. 626 permit exiting to IPv6 targets.
The latest consensus published in November contains:
- 6538 relays:
- 1562 of these (36.39% TCW) have an IPv6 ORPort.
- 1067 of these (24.86% TCW) support at least partial IPv6 reachability checks.
- 55 of these (1.90% TCW) support full IPv6 reachability checks.
- 2527 "usable guards" and Wgd=0.
- 641 of these (29.73% UGCW) support IPv6 clients.
- 446 of these (21.33% UGCW) support at least partial IPv6 reachability checks.
- 36 of these (2.92% UGCW) support full IPv6 reachability checks.
The IPv6 stats that we are collecting are:
- the number of Tor relays that support IPv6 reachability checks (full versus partial).
- the number of Tor relays that have an IPv6 ORPort.
- the number of connections, and consumed bandwidth, using IPv4 and IPv6.
- IPv6 bandwidth statistics.
Reminder that for relays to report IPv6 bandwidth statistics, they would have to set the option ConnDirectionStatistics to 1 and leave the ExtraInfoStatistics option enabled (it is on by default) to be able to report IPv6 bandwidth statistics. This is the relay operators’ decision, since relays are operated by volunteers. We will keep the statistics code in the codebase for when 0.4.5 is released and relays start reporting it.
在RIPE网站上发布的上一篇文章中，我们描述了2020年发生的有关为Tor网络提供IPv6支持的工作。
Tor 0.4.5.1-alpha是包含RIPE文章中描述的所有工作的第一个发行版。运行0.4.5.1-alpha的中继率先报告IPv6带宽统计信息。
Tor版本
截至2020年12月2日，网络上54％的中继运行支持IPv6的Tor版本。网络中的6852个中继中，有3587个正在运行0.4.4版，而8个中继正在运行最新的Tor版本0.4.5。从所有这些中，1588宣布了OR协议的IPv6地址和端口。目录机构可以在IPv6上访问1587个中继。 626允许退出到IPv6目标。
IP版本的继电器图
11月发布的最新共识包括：
6538继电器：
其中的1562个（TCW为36.39％）具有IPv6 ORPort。
其中的1067个（TCW为24.86％）至少支持部分IPv6可达性检查。
其中55个（1.90％TCW）支持完整的IPv6可达性检查。
2527“可用的警卫队”且Wgd = 0。
其中的641个（UGCW的29.73％）支持IPv6客户端。
其中的446个（占UGCW的21.33％）至少支持部分IPv6可达性检查。
其中36个（2.92％UGCW）支持完整的IPv6可达性检查。
IP版本已知的报告字节的分数
我们正在收集的IPv6统计信息是：
支持IPv6可达性检查（完整或部分）的Tor中继的数量。
具有IPv6 ORPort的Tor中继的数量。
使用IPv4和IPv6的连接数和消耗的带宽。
IPv6带宽统计信息。
提醒一下，要使中继报告IPv6带宽统计信息，他们将必须将选项ConnDirectionStatistics设置为1，并使ExtraInfoStatistics选项保持启用状态（默认情况下处于启用状态），以便能够报告IPv6带宽统计信息。这是中继员的决定，因为中继是由志愿者操作的。我们将在0.4.5发布时将统计代码保留在代码库中，然后中继开始报告它。
