1. I really like the addition of the final pop-router combo so its easy to follow connections. This has been missing in other suggestions so I am curious as to what others think.
I'm puzzled. Connections go from router to router. How does it help to say routerb-x-y-z-routerc.blah.net when routerc will show up as the next hop in the traceroute?
2. Using an fixed width format as proposed keeps the maximum length (not including the domain suffix) short. Assuming 2 digit router/interface numbers and a four digit DLCI, the max length is 24 characters. (Even if we allow 3 digits to router numbers we max at 29). I would propose to add a little more information in the form of 1 letter types in from of the numbers (like a 'd' before the DLCI number). Looking at the example above is marginally okay because all field are present but what if there was either no subinterface or no DLCI, how would you tell what the last number is supposed to mean?
As long as we are going to code router specific things in the DNS, they are going to be a wide variety of thing to indicate. We use the following scheme. <routername> - <interface designation> <slot number> - <card slot number> [<port number> [s <sub-interface number>].<pop>.cic.net. where interface designation is [fddi|hssi|ser|ether|fastether|atm|token|pos] i.e. um1-fastether3-0-0s1.ann-arbor.cic.net is the 1st sub interface of fastethernet in slot 3, card slot 0, port 0 of um1 router at our Ann Arbor POP.
3. How do people feel about putting the speed of the link in the DNS name, I have seen one yea and one nay. I am ambivilant, but leaning towards no,
Speed of the link is not important IMO.
4. Are people actually interested in pursuing this formally? If a spec was written would you change your DNS names to conform? Would you be willing
That depends on what's agreed on. Beauty is in the eye of the beholder, and so are names.
to set up a formal registration process with the IANA for 2(or 3) letter pop codes to be consistant?
If you wanted that, why not take the airport codes as many have already done? -dorian
