Best practice DNS alias name length
Posted on 2010-09-16
I need to create a DNS alias for a FQDN, to be configured (you could say "hard-coded") in configuration of an application to be installed on a number of PC's.
No user will be manually addressing the alias (e.g. such as www.mydomain.com) and the alias will be entered only once into application installation image.
On one hand I'd like a short alias name, but on the other I want to have a name which is clearly and easily indetifiable (such as applicationxyzlicenseserver.mydomain.com).
My DNS is integrated with Windows Server 2003/2008 AD.
1. What is the maximum length of a DNS alias name in DNS integrated with Windows Server 2003/2008 AD?
2. Can you refer to a best practice document/guide, which covers the recommended maximum length (if any) for a DNS alias?
3. Is there something I must be cautious about in regards to "a long" DNS alias name in DNS integrated with Windows Server 2003/2008 AD?
What I am not interested in:
Documentation/guide which describes creation of DNS alias, but does not mention the recommended length of the alias name.
