Ten years ago I was still telling a few customers that Novell Netware had supported TCP/IP since the early 90s and it was really time to shut off IPX, and the Appletalk users were at least running over IP, not LocalTalk, so I didn't have to care much, and the Windows people were probably already arguing about Active Directory and LDAP and whether to do DNS, DLSW was Not Dead Yet, and 1/3 of my X.25 customers acknowledged that it was way obsolete and time to join the 1990s (the other two were state governments who viewed it as Somebody Else's Emulation Problem.) The last time I was dealing with high-end Layer 1 access problems was a couple of years ago, but in addition to normal IPv4 and MPLS, I had customers running Fiber Channel and other SAN protocols on the WAN. There'll be enough IPv4 to keep antiques dealers in business for a while yet. -- ---- Thanks; Bill Note that this isn't my regular email account - It's still experimental so far.
