[arin-announce] WHOIS Notification
Today, Thursday, July 22, beginning at approximately 7:00 pm EDT (1900
UTC), ARIN will begin accepting queries to whois.arin.net via port 43 at
our co-location facility. In the past, some users have relied on the IP
address of whois.arin.net to direct queries. Please make sure in the
future to always rely on the host name. This is particularly important
during the upcoming weeks as we continue to make improvements to our
Today's scheduled improvement addresses port 43 whois. Port 80 queries
will continue to be served from the whois query box on ARIN's website at
www.arin.net or directly accessed at http://ws.arin.net/cgi-bin/whois.pl.
As we make additional improvements, it is equally important to direct port
80 queries to these targets, and not to whois.arin.net:80 or directly to
any IP address.
These changes, which come as a result of internal improvements to ARIN
WHOIS services, will include expanded port 80 coverage in the coming weeks
and improved failover capability. Thank you for your patience as we make
these improvements to better serve you.
