RE: Traffic to our customer's address(126.0.0.0/8) seems blocked by packet filter
Hi Thank you for your reply.
Makoto san, can you provide an ip-address within your assigned range that people can ping to test? You can ping to 126.66.0.30/8.

The following address blocks were allocated from IANA to APNIC on the 27th of JAN of 2005. Please refer to the following link. http://www.cymru.com/Documents/bogon-list.html --- Changes in version 2.6 (27 JAN 2005) 124/8, 125/8 and 126/8 allocated to APNIC (JAN 2005). Removed from the bogon lists. ---
Softbank BB (AS17676) was allocated 126/8 from APNIC, and Softbank BB (AS17676) immediately tried to use 126/8. However Softbank BB could not access the famous site using 126/8, It seems some of ISPs are blocking 126/8 due to outdated filter.
Ladies and gentlemen, please check the following URL! http://www.cymru.com/Documents/bogon-list.html
and if you find out you have outdated filter, please update the filter immediately.
Please let me know if you have any problem, concern or doubt regarding opening a filter for 126/8, please let me know.

Smurf. 'ping 126.255.255.255'.
How quickly they forget. :)
just remember that not all networks use '126.255.255.255' as a broadcast address. there are non-broadcast networks where that address is a 'host' one. []s, Marlon, CISSP.

i suspect not in this one interesting case, as the following ip address is part of a very special block, 127/8. randy

Most trojans for zombie networks provide this functionality. Connect to your favourite C&C server and issue; .advscan ping 42 2 64 126.X.X.X (this will ping the address space with 42 threads, using two second intervals for packets, the X's work as wildcards) After the scan has completed, issue .scanstats to view your results. If you need to stop the pinging in the interim, issue .scanstop to cease. Pete

%ping 126.255.255.255 works for some mutant stacks. plays old-hob w/ your arp cache tho. but i suspect that the /8 on the reference was either a typo from the original query or a vestigal remainder from the emacs buffer. pinging the indicated /32 gives me this: $ ping 126.66.0.30 PING 126.66.0.30 (126.66.0.30): 56 data bytes 64 bytes from 126.66.0.30: icmp_seq=0 ttl=235 time=311.999 ms 64 bytes from 126.66.0.30: icmp_seq=1 ttl=235 time=443.25 ms ^C --- 126.66.0.30 ping statistics --- 3 packets transmitted, 2 packets received, 33% packet loss round-trip min/avg/max = 311.999/377.624/443.25 ms from the IVTF conference hotel lobby. --bill

Just out of curiosity... are you going to continue to announce each individual /16 or will you consolidate to a single /8 announcement?
