6月14日,panabit派网发布了新版本TANGr5,重点针对IPv6的相关功能进行了大量更新。

看到这则消息,不禁联想到曾经感叹国内厂商对IPv6的重视程度之低(特别是在IPv6流量检测部分)。
总体来看,目前在政策的大力推动下基础设施及其提供商对于IPv6的重视程度在上升,而且已经实现了IPv6的大面积覆盖,例如华为、中兴、烽火等厂商的设备已经基本实现了IPv6覆盖,且功能完善,运营商商与终端设备厂商也随之跟进,基本实现了IPv6通网,但仍处于起步阶段,目前国内IPv6路由线路有时会乱窜而导致延迟高、丢包高、网络不稳定,进而导致体验较差(很多终端用户由于此原因而主动关闭IPv6网络),由此可见,目前运营商随按照政策要求完成了IPv6覆盖,但不愿意花费更多精力优化IPv6网络的使用体验,而导致IPv6网络只是“表面功夫”,实际生产生活中难以使用。
而对网络的更高需求,如DPI(深度包检测)、策略路由、流量日志、内容缓存等方面,则尚处于蛮荒阶段,大部分常用的企业路由、流量检测服务软硬件提供商(如维盟、爱快、海蜘蛛等)甚至尚未实现IPv6的基本覆盖(DHCPv6、RA、ND等均未实现)或仅实现了以上部分功能,而其DPI、策略路由等主力业务仍未在IPv6上实现。
派网Panabit也曾经是它们中的一员,但现在经过此次更新,体现了其对IPv6的重视,是真正愿意在此方面进行投入的,这对于中国的IPv6网络发展来说是一个好的趋势。
在此之前,也有一些服务商在此方面进行了投入,但他们更多是直接面向运营商(的招标)以及大企业,而对于一些小微企业和个人用户而言,基本是无感的。而此次的更新,让大量的小企业和个人用户也有能力部署与IPv4相当的IPv6网络,从而优化终端用户的IPv6使体验,让更多用户愿意使用IPv6(至少不主动关闭IPv6),改变对IPv6不稳定、体验差的刻板印象,这是一大进步。
另外,当前国内云服务商对于IPv6的重视更是低到离谱。
国内云服务商实现完整IPv6功能并投入使用的屈指可数(即使实现IPv6功能,也基本处于“测试阶段”),甚至大部分根本没有进行IPv6网络部署的计划。(这一点也体现在数据中心(IDC)对于IPv6的部署上)
当然,目前这一情况正在改善(但是个人觉得不容乐观)部分内容提供商为了降低成本(使用PCDN)开始进行IPv6部署(主要是流媒体),当然,也有一部分只是为了满足政策要求(部分提供商只是实现主域名的IPv6解析),这里点名批评bilibili,只有首页能使用IPv6,而且加载不全(纯IPv6环境下,由于cdn域名为纯IPv4,因此大量内容无法加载)。
反而是一些体量较小的云服务商正在努力部署IPv6(降低IP成本),甚至一部分小型云服务商已经开始提供IPv6 only服务了。
总之,任重而道远!

This web site truly has all of the information and facts I needed about this subject and didn’t know who to ask.
Hi my loved one! I want to say that this post is awesome, nice written and include approximately all vital infos. I would like to peer extra posts like this .
Thanks for your thoughts. One thing I’ve got noticed is banks in addition to financial institutions have in mind the spending behaviors of consumers and also understand that most people max out their cards around the getaways. They wisely take advantage of this particular fact and commence flooding ones inbox and snail-mail box by using hundreds of no interest APR credit card offers right after the holiday season concludes. Knowing that for anyone who is like 98 in the American public, you’ll rush at the chance to consolidate financial debt and switch balances for 0 apr interest rates credit cards.
