TCP Legal Names RFC952

by Wayne Maples [Published on 20 April 2004 / Last Updated on 20 April 2004]

The legal characters available for tcp host names are:
  • a-z
  • A-Z
  • 0-9
  • - (hyphen,the underscore is illegal)
  • . (dot)
Each protocol has naming conventions. The machine name / domain name combination configured at install follows NetBIOS conventions. When you install tcp/ip, the default tcp protocol machine name will default to the NetBIOS machine name. It can be left the same or changed. Each protocol can have a different machine name. If the NetBIOS machine name has illegal characters (for ip, legal for NetBIOS) such as the underscore, they will be converted to hyphens.
