SYMPTOMS
When you use all numeric NetBIOS computer names, some TCP/IP utilities will
misinterpret these NetBIOS names as IP addresses.
For example, if you have a computer named 4754755 and its IP address is
10.1.5.17. When pinging the computer, ping will misinterpret the computer
name as an IP address and will send an echo request to 0.72.141.67 rather
than 10.1.5.17. This will result in a request timed out error.
RESOLUTION
The use of all numeric NetBIOS computer names should be avoided when you
are using the TCP/IP protocol.
STATUS
This behavior is by design.

RFCs may be obtained via the Internet as follows:
Paper copies of all RFCs are available from the NIC, either individually or
on a subscription basis (for more information, contact NIC@NIC.DDN.MIL).
Online copies are available via FTP or Kermit from NIC.DDN.MIL as
rfc/rfc####.txt or rfc/rfc####.PS (#### is the RFC number without leading
zeros).
Additionally, RFCs may be requested through electronic mail from the
automated NIC mail server by sending a message to SERVICE@NIC.DDN.MIL with
a subject line of "rfc ####" for text versions, or a subject line of "rfc
####.PS" for PostScript versions. To obtain the RFC index, the subject line
of your message should read "rfc index".
