DNS zone files with more than one name pointing to the same IP

Question

I have set up a local DNS and the forward zone file looks like this:

$TTL 86400

@ IN SOA ns0.mylocal.loc. root.mylocal.loc. (

    2011071001  ;Serial
    3600        ;Refresh
    1800        ;Retry
    604800      ;Expire
    86400       ;Minimum TTL

)

@ IN NS ns0.mylocal.loc.

@ IN NS ns1.mylocal.loc.

@ IN A 192.168.100.58

@ IN A 192.168.100.59

@ IN A 192.168.100.100

@ IN A 192.168.100.125

ns0 IN A 192.168.100.58

ns1 IN A 192.168.100.59

srv2 IN A 192.168.100.100

srv3.mylocal.loc. IN A 192.168.100.125

srv4.mylocal.loc. IN A 192.168.100.125

srv5.mylocal.loc. IN A 192.168.100.125

Is this a correct form for declaring? Is there any other way to declare multiple names linked to one IP by means of the DNS?
