IPTT: (Time To Live):

 How many routers a datagram can 

pass through. Each router decrements this value by 1 until it 
reaches 0 when the datagram is discarded. This keeps 
misrouted datagram from remaining on the Internet forever 
Range: Any / Non-zero / Zero 
Any: Including all conditions for IPTTL 
Non-Zero: Including IPTTL is Non-Zero 
Zero: Including IPTTL is zero 

IP Fragment (IP Fragmentation Flag)

: Controls datagram 

fragmentation together with the identification field. The 
flags indicate whether the datagram may be fragmented, 
whether the datagram is fragmented, and whether the current 
fragment is the final one.   
Range: Any / Yes / No 
Any: Including all IP fragment case 
Yes: The ingress frame is fragmented packet 
No: The ingress frames is not fragmented packet 

IP Optio
