Note that in the 37/8, most traffic comes from TTLs around 100. These are Linux hosts. The smaller humps are at ~32 (Windows) and ~250 (Solaris).
I don't agree. TTL around 100 is most probably Windows hosts with initial TTL of 128. Everything below 64 can be Linux or FreeBSD. ~250 can be Solaris host but Cisco IOS also set initial TTL to 255. -- wbr, Oleg.
