Uhm....okay...but why does anyone prepend their ASN that much? Are you saying the Mikrotik did that on purpose?
MikroTik asks for an amount of prepends rather than what ASN to prepend with. There was a bug in an old version that would modulus the ASN with 256 and prepend that many times. In this case 39625 modulo 256 = 201 prepends.
