Class = IN = Internet Protocol

List of DNS record types - Wikipedia, the free encyclopedia


http://tools.ietf.org/html/rfc1035

3.2.4. CLASS values

CLASS fields appear in resource records. The following CLASS mnemonics
and values are defined:

IN 1 the Internet

CS 2 the CSNET class (Obsolete - used only for examples in
some obsolete RFCs)

CH 3 the CHAOS class

HS 4 Hesiod [Dyer 87]


BTW, names ending in '.' are not tried with domain name prefixes. Often, the domain is also a host, like an email or web server. If an email server, it may have a stub web server to redirect everyone to www.domain.

NAME
dnsextd -- BIND Extension Daemon SYNOPSIS
dnsextd DESCRIPTION
dnsextd is a daemon invoked at boot time, running alongside BIND 9, to implement two EDNS0 extensions to the standard DNS protocol. dnsextd allows clients to perform DNS Updates with an attached lease lifetime, so that if the client crashes or is disconnected from the net- work, its address records will be automatically deleted after the lease expires. dnsextd allows clients to perform long-lived queries. Instead of rapidly polling the server to discover when information changes, long-lived queries enable a client to indicate its interest in some set of data, and then be notified asynchronously by the server whenever any of that data changes. dnsextd has no user-specifiable command-line argument, and users should not run dnsextd manually. SEE ALSO
mDNS(1) mDNSResponder(8) For information on Dynamic DNS Update, see RFC 2136 "Dynamic Updates in the Domain Name System (DNS UPDATE)" For information on Dynamic DNS Update Leases, see http://files.dns-sd.org/draft-dns-update-leases.txt For information on Long-Lived Queries, see http://files.dns-sd.org/draft-dns-llq.txt BUGS
dnsextd bugs are tracked in Apple Radar component "mDNSResponder". HISTORY
The dnsextd daemon first appeared in Mac OS X 10.4 (Tiger). Darwin June 1, 2019 Darwin
