as a practical matter, this was true even in IPv4. yes, you can often use address literals in either v4 or v6 apps, but this isn't practical for ordinary users on an ordinary basis. and in both v4 and v6, several essential apps (e.g. email, the web) have explicit dependencies on DNS. yes you can use address literals in email addresses and URLs but there is no assurance that an email address or URL with an address literal is equivalent to the same address or URL with a domain instead of the address. Both email and the web define their resources in relation to a DNS name, not relative to a host or address. of course it is possible to write apps that do not use DNS, but this is rarely done. Keith
