Estou recebendo esse prefixo via PTT-RS e está funcionando normalmente.
Existe um firewall bloqueando icmp/udp.

Veja:

Nmap com ICMP:

# nmap -v -PE 201.94.10.88

Starting Nmap 5.00 ( http://nmap.org ) at 2009-11-05 00:58 BRST
Initiating Ping Scan at 00:58
Scanning 201.94.10.88 [1 port]
Completed Ping Scan at 00:58, 2.01s elapsed (1 total hosts)
Read data files from: /usr/share/nmap
Note: Host seems down. If it is really up, but blocking our ping probes, try
-PN
Nmap done: 1 IP address (0 hosts up) scanned in 2.27 seconds
           Raw packets sent: 2 (56B) | Rcvd: 2 (152B)


Nmap normal:
