The TXT RR is used by ISC's dhcpd to record client
identities in DNS. I haven't been able to track
this back to any DHCP specification.
Is TXT RR the one for the domain itself or is there one per host? If the
later, I don't see any conflict. Could you post an example?
This is from the dhcpd.leases man file:
# The ddns-text variable
#
# The ddns-text variable is used to record the value of the client's TXT
# identification record when the interim ddns update style has been used to
# update the DNS for a particular lease.
(I found a copy of it at
http://linux.com.hk/PenguinWeb/manpage.jsp?section=5&name=dhcpd.leases)
This was from a message in an archive somewhere:
(http://www.seattlewireless.net/pipermail/dev/2001-November/004968.html)
# A note about using TXT records and dhcpd servers (in this case
# ISC dhcpd 3.0):
# When the DHCP server issues a client a new lease, it cre-
# ates a text string that is an MD5 hash over the DHCP
# client's identification (see draft-ietf-dnsext-dhcid-
# rr-??.txt for details). The update adds an A record with
# the name the server chose and a TXT record containing the
# hashed identifier string (hashid). If this update suc-
# ceeds, the server is done.
#
#
# Sure enough, when running in ddns-update-style interim these records
# are added:
#
# nitrous TXT "313fe40368e0c95848c336d33f7dd03bc7"
# A 10.100.3.252
