Re: ICMP type 8 code 80?

I could be wrong but a type = 8 means an echo request, I believe that a code = 30 means Traceroute.

Subject: [Snort-users] ICMP type 8 code 80?

I received a number of these early today:

------------------------------------------------------------------------
Count:1 Event#8.306289 2012-07-26 10:37:35 GPL ICMP undefined code
67.220.42.22 -> 192.168.13.92
IPVer=4 hlen=5 tos=0 dlen=60 ID=27393 flags=0 offset=0 ttl=13 chksum=1738
Protocol: 1 Type=8 Code=30 chksum=17093 ID=46085 seq=0
Payload:
83 C7 2E 00 EF BE AD DE EF BE AD DE EF BE AD DE ................

Anybody have a clue what ICMP Type 8 Code 30 might mean?
