Description

16 years ago
User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3) Gecko/20030312
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3) Gecko/20030312

My home web site is on DSL using dynamic IP addressing. The IP address changes
every ten days or so. If I have Mozilla open durin the period when the IP
changes, then untl I restart my PC Mozilla continues to try the old IP instead
of the new IP.

Reproducible: Always

Steps to Reproduce:
1. Open Mozilla
2. Goto a web site. It will load. Use a URL, not an IP address.
3. Change the IP address of the web site
4. Goto the web site again using the same URL. It will fail to load as it is
using the old IP address instead of the new.

Switching Mozilla between offline and online operation should be enough to unpin
the IP address (though I guess not in version 1.3, see bug 192798)

Mozilla is currently "pinning" the IP address as a security precaution. 
Obviously some smarter behavior is needed, and there are a number of bugs open
on this.

Bug 198594 - allow Reload to reload the DNS info
Bug 151929 - DNS TTL support
Bug 168566 - support for network.dnsCacheExpiration
Bug 162871 - problem with pinning forever

VERIFIED/dupe.

why are the bug descriptions getting longer and longer? please keep them to 60
characters. most mailers and bugzilla queries won't display summaries beyond
that length.
