Hi all,
We are seeing odd behaviour when attempting to look up the following url
from a range of Redhat servers.
bigmail1.lycosmail.lycos.com should resolve to 209.202.248.251 but we see
the following.
[xx at xxxx ~]$ host bigmail1.lycosmail.lycos.com
Host bigmail1.lycosmail.lycos.com not found: 2(SERVFAIL)
But then if we
[xx at xxxx~]$ dig -t any bigmail1.lycosmail.lycos.com
; <<>> DiG 9.3.4-P1 <<>> -t any bigmail1.lycosmail.lycos.com
;; global options: printcmd
;; Got answer:

And then
[xx at xxxx~]$ host bigmail1.lycosmail.lycos.com
bigmail1.lycosmail.lycos.com is an alias for mail-bigmail1.bo3.lycos.com.
mail-bigmail1.bo3.lycos.com has address 209.202.248.251
errors we see in the bind log

The expected subdomain is returned, the only other FORMERR cases I’ve seen
(on google) show the authority section not matching the answer.
A debug trace may be found at

Any suggestions as to what the issue is or how it may be resolved would be
very welcome.
Kind Regards
Matt
