Aren't networks fun?
Aug. 12th, 2011 07:54 pmMy ISP can't decide which IP address it should give me for a particular domain:
C:>nslookup [domain removed] Non-authoritative answer: Name: [domain removed] Address: 74.54.206.194 C:>nslookup [domain removed] Non-authoritative answer: Name: [domain removed] Address: 74.53.204.214 C:>nslookup [domain removed] Non-authoritative answer: Name: [domain removed] Address: 74.54.206.194 C:>nslookup [domain removed] Non-authoritative answer: Name: [domain removed] Address: 74.53.204.214
I changed it from 74.54.206.194 to 74.53.204.214 last night. My registrar uses a TTL of 1 day, so presumably one of my ISP's resolvers queried it while I had the old address and the other after I changed it. And now it's pot luck which resolver a DNS request will be routed to (as both are hiding behind the same IP address). This is a wonderful example of failing at maintaining a coherent cache.
