Is it valid for a hostname to start with a digit? e.g. 8server
From reading RFC 1123 it would appear that this is a valid hostname. However, I'm not clear on whether a hostname can only start with a digit when there is a suffix e.g. 8server.com
The origin of this question is that InternetDomainName.isValid("8server");
in the Google Guava library (Javadoc) rejects the input. I also posted a specific question on the Guava Discuss group.
