======================================================

The TOS field is 8 bits, ALL values are valid....0 to 255

0x62 is a packet from the 6 (src) to the 2 (dst) address space...

1-bit to set the Reserved/Spare ("SNOOPY") bit in Fragment Offset [S]
1-bit to set the Don't Fragment (DF) bit [D]
2-bits to select 1 of 4 common TTL values (255, 128, 32, 8) [LL]
1-bit for Options Control [O]
7-bits to set the Identification Field(dst) [FFFFFFF]
