+Subject: [PATCH] [release-branch.go1.22] net/netip: check if address is v6
+ mapped in Is methods
+
+In all of the Is* methods, check if the address is a v6 mapped v4
+address, and unmap it if so.
+
+Thanks to Enze Wang of Alioth (@zer0yu) and Jianjun Chen of Zhongguancun
+Lab (@chenjj) for reporting this issue.
