Re: Catalog of IPv4 literals

[bmanning@vacation.karoshi.com]

if an application "breaks" becuase someone uses an address literal instead
of a domain name, then that application is itself broken.  the DNS translates
the name into an address and the address is used...  so whether a name or
a literal is handed to the app should be immaterial.  

so your "catalog" of address literals is really the full set of all IP addresses.
