Pollard's Kangaroo method also uses a start and end range. However, it does not support strides (AFAIK) because Pollard's Kangaroo algo is using it's own kind of stride while making the tame and wild kangaroos hop. There's no way to tell Kangaroo: "OK, there is a part of the private key at the end that's already known, don't search those bits". The consequence is that for this particular situation, Kangaroo will take longer to find the PK (way too long actually).
