Stability Concerns
- DNS stability is very important for the stability of the WWW
- Stability has various aspects:
- Stability over time: Very important for the Web, but not guaranteed
by DNS
- Stability over location of query: Guaranteed by DNS, should stay
that way
- Stability depending on software and setup: dito
- Resolution guaranteed vs. failure possible: The Internet may always
fail
- Same address vs. same content vs. similar content (distributed
servers, mirroring)
