The routine _iiii_nnnn_eeee_tttt______mmmm_aaaa_kkkk_eeee_aaaa_dddd_dddd_rrrr takes an Internet network number and a local network address and constructs an Internet address from it. The routines _iiii_nnnn_eeee_tttt______nnnn_eeee_tttt_oooo_ffff and _iiii_nnnn_eeee_tttt______llll_nnnn_aaaa_oooo_ffff break apart Internet host addresses, returning the network number and local network address part, respectively. The routine _iiii_nnnn_eeee_tttt______nnnn_tttt_oooo_aaaa returns a pointer to a string in the base 256 notation "_d_...._d_...._d_...._d_"""" _dddd_eeee_ssss_cccc_rrrr_iiii_bbbb_eeee_dddd _bbbb_eeee_llll_oooo_wwww_.... All Internet addresses are returned in network order (bytes ordered from left to right). All network numbers and local address parts are returned as machine format integer values. IIIINNNNTTTTEEEERRRRNNNNEEEETTTT AAAADDDDDDDDRRRREEEESSSSSSSSEEEESSSS Values specified using the `_....' notation take one of the following forms: _aaaa_...._bbbb_...._cccc_...._dddd _aaaa_...._bbbb_...._cccc _aaaa_...._bbbb _aaaa When four parts are specified, each is interpreted as a byte of data and assigned, from left to right, to the four bytes of an Internet address. When a three part address is specified, the last part is interpreted as a 16-bit quantity and placed in the right most two bytes of the network address. This makes the three part address format convenient for specifying Class B network addresses as "128.net.host". PPPPaaaaggggeeee 1111 iiiinnnneeeetttt((((3333NNNN)))) iiiinnnneeeetttt((((3333NNNN)))) When a two part address is supplied, the last part is interpreted as a 24-bit quantity and placed in the right most three bytes of the network address. This makes the two part address format convenient for specifying Class A network addresses as "net.host". When only one part is given, the value is stored directly in the network address without any byte rearrangement. All numbers supplied as "parts" in a `_....' notation may be decimal, octal, or hexadecimal, as specified in the C language (that is, a leading 0x or 0X implies hexadecimal; otherwise, a leading 0 implies octal; otherwise, the number is interpreted as decimal).

NNNNOOOOTTTTEEEESSSS The problem of host byte ordering versus network byte ordering is confusing. A simple way to specify Class C network addresses in a manner similar to that for Class B and Class A is needed. The return value from _iiii_nnnn_eeee_tttt______nnnn_tttt_oooo_aaaa points to static information which is overwritten in each call. PPPPaaaaggggeeee 2222
