Quite right Eric. My apologies everyone.
Here follow the recent references:

NAPTR  stands for Naming Authority
Pointer [1] and is a newer type of DNS record that supports regular _expression_
based rewriting. Several NAPTR records can be chained together creating
fairly sophisticated URI rewriting rules. A record can go through any number
of rewrites before reaching a terminal condition.  -  this is
actually much simpler than the example listed in Wikipedia would lead one
to believe at first. Section 13.3 (page 26) of the LSID specification [2]
has a relatively straightforward explanation of how this can work.

DDDS or The Dynamic Delegation Discovery
System [3] [4]  is used to implement lazy binding of strings to data,
in order to support dynamically configured delegation systems.  

SRV or Service Record Service record
[5] is a category of data in the Internet Domain Name System specifying
information on available services.  

LSID or Life Science Identifier [6]
-  for those who want to know what these really are and what they
were created  for, please read this overview
