Question about pages 17 and 18, of 49, at http://www.nanog.org/meetings/nanog45/presentations/Sunday/RAS_traceroute_N45.pdf
It is mentioned that prefixes and numbers in DNS (when doing traceroute) are specific to each vendor of network equipment.
An example is given of making sense of
- XE-#/#/# is Juniper 10GE port. The device has at least 12 slots.
- It’s at least a 40G/slot router since it has a 10GE PIC in slot 1
- It must be Juniper MX960, no other device could fit this profile.
How exactly does this work? Do vendors provide special tools for generating and managing DNS records? Or what is this based upon?
