Bell's ARIN records show 102.108.206.in-addr.arpa delegated to 
nameservers named under bell-nexxia.net, which is a zone that Bell do 
not currently run.

If you believe the dates returned by whois.crsnic.net, 
"bell-nexxia.net" was only recently registered, while "bellnexxia.net" 
was registered in 1999.

Maybe someone at Bell typo'd nameserver names when they filled out the 
paperwork for 206.108/20, and someone else got fed up with waiting for 
them to fix it (and hence the reverse DNS for these blocks).
