Hello,
Yes, Lightsail is revising instance bundle pricing to accommodate IPv4 and new pricing will be published later this year. We understand the importance of bundled and predictable pricing for Lightsail, so revised pricing will include the IPv4 conservation charge in a monthly bundle cost and not as a separate charge.

lightsail似乎是整体涨价，不是$3.5另加IPv4的费用
我特么还没体验呢，就要涨价了，还有steam阿区也一去不复返了，双重打击 
涨价不用不就行了，aws的jp也拉胯了
光帆reboot又不会改ip, 大不了ddns呗, 还是很香, ip抢了就换
@Slotheve #2 动态ip依然免费吗？
@aom233 #3
对啊, 开始收费的只是静态ip
@Slotheve #4 那还确实没啥影响
@aom233 #3 整体涨价，以后没有3.5刀的了
