IPv6 ISATAP address

These are ISATAP address:
2001:836b:4:8000:0:5efe:10.0.0.20    
2001:836b:4:8000:200:5efe:131.107.0.32

I am confused on the 2nd one where the embedded IP address is a public IP address. I thought that ISATAP can only use in an intranet environment.

Thanks

ISATAP stands for Intra-site Automatic Tunnel Addressing Protocol. That means ISATAP is used on an "intra-site" or on local network. It is not used on Internet.
However, ISATAP supports and can be used with both public and private IP addresses. But on intranet or private networks.

ISATAP address format consists of two parts: 64 bit IPv6 prefix and IPv6 interface ID. This is like an IPv4 network and host ID.

ISATAP IPv6 Interface ID can be either:
1. ::0:5efe:w.x.y.z, if the IPv4 address is a private IP address
or
2 ::200:5efe:w.x.y.z, if the IPv4 address is a public IP address
