    Karl is definitely quite right that cached records still continue to float about and are not immediately updated. This is usually the case at ISPs, where DNS records are often cached anywhere from one hour to several hours to perhaps even a day.

    I'm not sure how the system could be improved much, except to take out the caching of DNS records at the ISP level. However, this would add considerable extra load to the Internet root servers as every ping, every lookup, and the like would query the root servers. So, in that sense, cached records at ISPs are a good part to the whole DNS system and probably should not be eliminated.

    Does anyone know of any way to improve the problem with cached records? I was thinking to have the IETF issue a specific time standard for all ISPs to follow when caching DNS hostnames. Something like one hour, or perhaps two at the most.

    I'm not a technical expert, but it seems like a good idea. Anyone?

    Cheers,
    Doug
