the %25 uauage of IPv6 on Window 7


  • I am expericing IPV6 on window, and confused with the field after IPv6 address. when I ping the device, I use IPV6 follow with %11 or not, both works.  11 is the sscopeID of mocal link interface  When I put IP address in RUL on IE, with or without %11 also ok.  But sometime window 7 auto insert %25 after IPv6 address.  Why is that.  When the %25 should be used?  Thank you.

  • Hi,


    Based on my research, the “%25” just means the network interface for the network adapter. It is not a valid character for IP addresses. For more information about IPv6 and the percentage symbol, please refer to the link below:
