I am a bit confused about IP ID and was wondering about the following.
Is it normal to have the same IP ID for the initial SYN packet from different source IP addresses? There is no fragmentation issues in this case since it is only 40 bytes and I see this same IP ID only with attempts to establish a session to 161/TCP.
I read through RFCs (mostly 6861 and 4413) but not sure. Please let me know if you can give me any clues or suggestions.
Thanks very much,
Vijay
