I seem to recall your involvement with these unknowing, misleading people: http://www.menandmice.com/2000/2330_enterprise_bind.html. As apparent via Google search, "DNS propagation" has widely understood meanings in both public (non-authoritative) and private (authoritative) contexts. Vis-a-vis authoritative servers, it refers to the "pull replication" of zones, taking up to one refresh interval to take effect in toto (barring use of NOTIFY). Vis-a-vis the public Internet, it refers to the "pull replication" of records, taking up to the max TTL to take effect in toto. I agree that "propagation" is an slightly off-base term given the dictionary definition. It may seem to connote a "push replication" or "broadcast" to some, which of course it is not. But the observed effect is the same--gradual replication of the most-recently-entered data. Even if, yes, the TTL concept states that the most-recently-entered data should not be considered to "exist" in a global sense until the TTL expires, there's nothing particularly wrong with the impression of propagation, as long as the person using the term knows what's happening under the surface. --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.mailmage.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange or IMail mailboxes into IMail Aliases! http://www.mailmage.com/products/software/freeutils/exchange2aliases/download/release/ http://www.mailmage.com/products/software/freeutils/ldap2aliases/download/release/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
