"n", "h' "l", and "i". Thus, a host table address may be represented

as: "n.h.l.i". Each of these four numbers will have either one, two,

or three decimal digits and will never have a value greater than 255.

For example, in the host table, address: "10.2.0.124", n=10, h=2, l=0,

and i=124. To convert a host table address to a MILNET X.25 address:

1. If h < 64, the host table address corresponds to the X.25

ZZZZ F IIIHHZZ (SS)

where:

ZZZZ = 0000 as required

III is a three decimal digit respresentation of

zeros if required;

HH is a two decimal digit representation of "h",

if required;

ZZ = 00 and

(SS) is optional

In the example given above, the host table address 10.2.0.124

corresponds to the X.25 physical address 000001240200.

2. If h > 64 or h = 64, the host table address corresponds to the

ZZZZ F RRRRRZZ (SS)

where:

ZZZZ = 0000 as required

RRRRR is a five decimal digit representation of

the result "r" of the calculation

r = h * 256 + i

(Note that the decimal representation of

"r" will always require five digits);

ZZ = 00 and

(SS) is optional

Thus, the host table address 10.83.0.207 corresponds to the X.25

In both cases, the "n" and "l" fields of the host table address are

not used.
