Yes, but there is no way to get its name from a reverse lookup, i.e, its
ip address doesn't report the name 'm206-157.dsl.tsoft.com' as a valid
host hooked to it.

$ dig m206-157.dsl.tsoft.com
.......
;; QUESTION SECTION:
;m206-157.dsl.tsoft.com.                IN      A

;; ANSWER SECTION:
m206-157.dsl.tsoft.com. 3600    IN      A       198.144.206.157


Now, let's do the reverse lookup.

$ dig -x 198.144.206.15

; <<>> DiG 9.2.2 <<>> -x 198.144.206.15
