Yes, the point is a bit pedantic in this context. On the other hand the RFC gives you a lot more rope: - example TLD and all sub-domains. - example.com 2LD and all sub-domains - example.org 2LD and all sub-domains - example.net 2LD and all sub-domains > I am pretty sure there is even an RFC that states http://tools.ietf.org/html/rfc2606 > to use example.com.

This is IANA reserved address space, if this is not a black-hole, the packets received are used for research... See also: http://tools.ietf.org/html/rfc3330 192.0.2.0/24 - This block is assigned as "TEST-NET" for use in documentation and example code. It is often used in conjunction with domain names example.com or example.net in vendor and protocol documentation. Addresses within this block should not appear on the public Internet. http://tools.ietf.org/html/rfc3849 To reduce the likelihood of conflict and confusion when relating documented examples to deployed systems, an IPv6 unicast address prefix is reserved for use in examples in RFCs, books, documentation, and the like. Since site-local and link-local unicast addresses have special meaning in IPv6, these addresses cannot be used in many example situations. The document describes the use of the IPv6 address prefix 2001:DB8::/32 as a reserved prefix for use in documentation.
